B.) fine and interpret the probability that exactly 13 flights are on time.
C.) find and interpret the probability that fewer than 13 flights are on time.
D.) find and interpret the probability that at least 13 flights are on time.
E.) find and interpret the probability that between 11 and 13 flights, inclusive, are on time.

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
