A.
The experimental probability is 35%.

B.
The experimental probability is 65%.

C.
The theoretical probability is 35%.

D.
The theoretical probability is 65%.

Answer 1

@Yinshy
Lets start by concluding whether the probability is theoretical or experimental.
What is your guess?

Answer 2

theoretical

Answer 3

100-35 = 65
it means, The theoretical probability is 65%.

Answer 4

Answer 5

Answer 6

Correct.
Now, here is something interesting.
If we do 100 - 35, it equals 65.
If we do 100 - 65, it equals 35.
If 35 buttons with cats were drawn, then the theoretical probability would be 65%.

And apparently someone is determined to help you before I do, but I hope you understand. :)
