Question

yasmine is playing a true false geography game. She has answered 15 of her 20 questions correctly. What is the probability that she will answer the five remaining questions correctly

Answer 1

100%

Explanation:

We know

She has answered 15 of her 20 questions correctly.

What is the probability that she will answer the five remaining questions correctly?

We take

15/15 = 100%

So, 100% she will answer the five remaining questions correctly.

Answer 2

1/32

Explanation:

Assuming that each question is independent, the probability of Yasmine answering a question correctly is 1/2, since each question has two possible answers (true or false) and she has a 50/50 chance of guessing correctly. Therefore, the probability of her answering all five remaining questions correctly is:

(1/2)^5 = 1/32

So the probability of Yasmine answering the five remaining questions correctly is 1/32, or approximately 0.03125, or about 3.125%.
