4. Five individuals from an animal population thought to be near extinction in a certain region have been caught, tagged and released to mix into the population. After they have had the opportunity to mix, a random sample of 10 of these animals is selected without replacement. Let X represent the number of tagged animals in the second sample. Suppose there are actually 25 animals of this type in the region. (a) Find the probability that fewer than 2 of the animals are tagged in the second sample. (b) Find P(3< X ≤ 5).
