Johanna is trying to find the probability that a cup will land open end up. She takes a cup and tosses it in the air 1000 times and each time records if it lands open end up or open end down. She finds that 630 times the cup lands open end up. Do the outcomes of the cup appear to be equally likely?

Don't you think it would end up on its side most often ????

It is possible that the cup could land on its side, but the question specifically asks about the probability of the cup landing open end up or open end down. Without additional information, it is impossible to determine the probability of the cup landing on its side.
