Statistics (I think it is B)?

Question

You take a surprise quiz in your astronomy class with 8 multiple questions. You estimated that you would have about a 70% chance of getting any individual question correct. What are your chances of getting them all right? Your simulation should use at least 20 runs.

A: 4.28709385
B: 5.6
C: 0.05764801
D: 56
E: 2,097,152

Answer 1

If you have a 70% chance of getting each question right, the chance of getting 8 questions right is...

(70%)^8
= (0.7)^8
= 0.05764801
= 5.76% chance

Answer 2

8 * 70% = 5.6
For me the answer is letter B.
