There are 6 possible outcomes. And there are 2 outcomes that are not less then 5 which is 6 & 5. So you would get 2/6 or about 33%.

**Answer:**

The probability is 0.152

**Step-by-step explanation:**

We know that in this town 39% of all voters are Democrats. Therefore, the probability of a randomly selected voter being a Democrat is

The experiment of randomly select voters for a survey is called a Bernoulli experiment (under some suppositions). We suppose that exist independence in this randomly selection of voters. We also suppose that there are only two possibilities for the voter : It is Democrat or not.

Now the variable X : ''The randomly selected voter for a survey is Democrat'' is a Binomial random variable.

X ~ Bi (n,p)

The probability function for the BInomial random variable X is :

Where ''n'' is the number of Bernoulli experiments (In this case n = 2 because we randomly selected two voters)

P(X=x) is the probability of the variable X to assumes the value x

(nCx) is the combinatorial number define as

p = 0.39 in this exercise.

We are looking for P(X=2) ⇒

If we round to the nearest thousandth the probability is 0.152

QUESTION POSTED AT 01/04/2020 - 01:15 PM

The given is 860 calculators with a possibility that 9 are defective. To calculate for simple probability, we should have a number of desired outcomes (890) and number of possible outcomes (9). To calculate this, we have: 9 divided by 890 which equals to 0.0104. To get the percentage, we multiply 0.0104 by 100 and we'll have 1.04%. So, there's a 1.04% probability that a calculator chosen at random will be defective.

I'll do the first one:

Both novels.

Student 1 picks a novel. There are 3 novels out of 6 books total.

Now there are 5 books left.

Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.

To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.

So the probability is 1/5. Or 20%

QUESTION POSTED AT 29/03/2020 - 06:29 PM

**Answer:**

Option C

**Step-by-step explanation:**

A and B are said to be independent of

P(A intersection B) = P(A)*P(B).

Or if drawing is done with replacement, etc.

A) P(drawing a king) = 4/52 = 1/13

IF we replace again drawing a kind is the same 1/13

Hence independent

B) Coin flipping each toss is obviously independent of the other as prob of getting tail in a fair coin is 1/2 irrespective of the previous outcomes

C) Without replacement is not independent

Since first prob = 4/52 and second would be 3/51 not the same as before

D) Rolling a die is independent as getting a 2 in any throw is always the same.

C is answer

**Answer:**

There is a 6.67% probability that a nickel is drawn first and then a quarter.

**Step-by-step explanation:**

There are 6 coins. The sum of their values is $0.67. We need to find how many of each coin are there.

A penny is worth 1 cent.

A nickel is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

**To get to 67 cents, we need:**

Two pennies, a nickel, a dime and two quarters.

**So:**

**What is the probability that a nickel is drawn first and then a quarter? Assume no replacement and that all coins are equally likely.**

Initially there are 6 coins, of which 1 is a nickel. So the probability that the nickel is drawn is:

There are no replacements, so now there are 5 coins, of which 2 are quarters. So the probability that a quarter is drawn is:

.

**The probability that a nickel is drawn first and then a quarter is:**

There is a 6.67% probability that a nickel is drawn first and then a quarter.

**probability that the arrow will stop on the same letter twice = (c).**

**Step-by-step explanation:**

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = .

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6. Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability = .

Probability = .

**Therefore, probability that the arrow will stop on the same letter twice = (c).**

It is .277

because there are 26 letters in the alphabet, and 10 numbers given (0-9)

add both amount of characters: 26+10=36

then put a number of numbers over the total amount of characters: 10/36

now divide 10 by 36

and you will get .277777, but since you said by the nearest hundredth, estimate and get
