Assume that a flower bed contains 40 flowers. Suppose that 8 of the flowers are white, 8 of the flowers are pink, 8 are yellow, 8 are orange, and 8 are green. Suppose that 10 flowers are randomly selected, without replacement. What is the probability that exactly 2 of the flowers are yellow, exactly 4 of the flowers are another common color and exactly 4 of the flowers are a third common color

Assume that a flower bed contains 40 flowers. Suppose that 8 of the flowers are white, 8 of the flowers are pink, 8 are yellow, 8 are orange, and 8 are green.
Suppose that 10 flowers are randomly selected, without replacement. What is the
Expert Solution
Step 1
Introduction:
If r distinct items are to be chosen from n items without replacement so that the order of selection is immaterial, then the number of possible selections can be obtained using the combination rule, with (nCr) = n! / [r! (n – r)!] = [n (n – 1) … (n – r + 1)] / r!
