Assume that z scores are normally distributed with a mean of 0 and a standard deviation of 1. if p(z >

madreJ [45]

Given that μ=0, and σ=1, P(z>c)=0.1093
thus
P(z<c)=1-0.1093=0.8907
hence the value of c will be:
z-score=(c-μ)/σ
thus
1.23=(c-0)/1
c=1.23

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
