Question

A large box contains buttons with pictures of animals.

There are four different animals. A button is drawn and replaced. In 100 trials, 35 buttons with cats were drawn.

What is the probability that the next button will be a different animal?

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

The experimental probability is 65%.
In reality, there are 4 animals so the theoretical probability would be 3/4, or 75%. Within the bounds of the experiment, the other animals make up 65% of the trials, so the experimental probability would be 65%.
