Answer 4

Can you explain please (The Unit test is gonna eat me alive if idk)

Answer 5

sure:)

Answer 6

B right, Because it's 3 times the same experiment.

And in each experiment, P(A)=1/4, P(B)=1.4n P(C)=1/4 and P(D)=1/4.
Therefore, "A then B then C" has a (1/4) * (1/4) * (1/4) probability of happening.

Answer 7

Well if those are the only 3 options of a segment, then there is a 1/3 chance of landing on A, then a 1/3 chance of landing on B, then a 1/3 chance of landing on C. Multiply the fractions together to get 1/27. However that isn't one of your answers. I'm thinking that the spinner has 4 sections, meaning 1/4 chance of A, then 1/4 chance of B, then 1/4 chance of C. Multiply these together to get 1/64, which is one of your answers. That's my input anyway

Answer 8

thats how I figured it out..
