Eddi Din [679]
Simple,

writing out the problem...

The probability that a person in the United States has type B​+ blood is 13​%.
blondinia [14]

Answer:

Step-by-step explanation:

Given that the probability that a person in the United States has type B​+ blood is 13​%.

Since four unrelated people in the United States are selected at random, we can say that each person is independent of the other to have B+ blood group.

Let X be the number of persons who have blood group B+ in the group of 4 persons.

X is Binomial with p = 0.13

a) P(X = 4) = (0.13)^4 = 0.000286

b) P(x =0) = (1-0.13)^4 = 0.572898

c) P(X\geq 10 = 1-P(0) = 0.427102

d) All having B+ is unusual since probability is very negligible
