Answer:
16 cm
Step-by-step explanation:
Circumference is equal to 2 pi r.
Isolating r gives us C/2pi = r
50.26/2pi = 8, exactly.
Diameter is equal to 2r, so the diameter is 16 cm.

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) = 
b) P(x =0) = 
c) 
d) All having B+ is unusual since probability is very negligible
