Astandard number cube is rolled 288 times. predict how many times a 3 or a 5 will be the result. 58 times 93 times 96 times 99 times

The events of rolling a 3 or a 5 are disjoint, so .

Each face has a probability of occurring, so the event of interest occurs with probability . The number of times a 3 or 5 is rolled across 288 trials has a binomial distribution, .

Recall that the expected value of a binomial distribution is . So in this experiment, we should expect to witness approximately instances of rolling a 3 or a 5.
