BabaBlast [244]

Complete question is;

Multiple-choice questions each have 5 possible answers, one of which is correct. Assume that you guess the answers to 5 such questions.

Use the multiplication rule to find the probability that the first four guesses are wrong and the fifth is correct. That is, find P(WWWWC), where C denotes a correct answer and W denotes a wrong answer.

P(WWWWC) =

Answer:

P(WWWWC) = 0.0819

Step-by-step explanation:

We are told that each question has 5 possible answers and only 1 is correct. Thus, the probability of getting the right answer in any question is =

(number of correct choices)/(total number of choices) = 1/5

Meanwhile,since only 1 of the possible answers is correct, then there will be 4 incorrect answers. Thus, the probability of choosing the wrong answer would be;

(number of incorrect choices)/(total number of choices) = 4/5

Now, we want to find the probability of getting the 1st 4 guesses wrong and the 5th one correct. To do this we will simply multiply the probabilities of each individual event by each other.

Thus;

P(WWWWC) = (4/5) × (4/5) × (4/5) × (4/5) × (1/5) = 256/3125 ≈ 0.0819

P(WWWWC) = 0.0819

Find the slope of the line that passes through the given points.<br> (-5,6) and (2,6)
CaHeK987 [17]

Answer:

0

Step-by-step explanation:

Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.

In this case, the change in y was 6 - 6 which equals 0.

The change in x was -5 - 2 which was -7.

Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.

Therefore, your answer would be 0.

I hope this helped :)
