Question

Joe has to take two quizzes tomorrow. He has only enough time to study for one of them. The science quiz has 6 true or false questions. The english quiz has 4 multiple choice questions.

Answer 1

Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

Answer 2

The quiz he should study is; English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).

How to find Probability?

We are told that for science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

Thus;

P(6) = 0.5⁶ = 0.016

We are told that for English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

Thus; P(4) = 0.25⁴ = 0.004

Thus, we conclude that they will have to study English because the probability of getting all questions correct is 0.004 which is lower than for science (0.016).
