A student practices flipping a water bottle to land standing
up on a table. After 60 attempts, he records he was
successful on 23 attempts.

Using his experimental probability, should he bet his friend that he can make it land standing up at least 4 times out of 10
tries?

Yes, he should be able to get 4 out of 10 easily

No. He won't come close to getting 4 out of 10.

Maybe. It should be really close to 4 times out of 10.

The only way he can get 4 flips to land right is doing it 100 times.
