The probability of owning a cat is 20% in some population. For 10 randomly chosen people, what is the probability that exactly 5 own a cat but in any order of selection. Give your answer as 0.XX.
We have here, n = 10 and p = 0.20
=0.0264

People with blood type O- are sometimes referred to universal donors as their blood can be used for all recipients. About 9% of the Australian population have blood type 0-. Suppose blood donors have the same distribution of blood types as the Australian population. In any 10 donors chosen at random, what is the probability that exactly 3 will have O- blood? In any 10 donors chosen at random, what is the probability that between 1 and 4 inclusive will...
