Answer:
The probability that all three have type B+ blood is 0.001728
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have type B+ blood, or they do not. The probability of a person having type B+ blood is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
The probability that a person in the United States has type B+ blood is 12%.
This means that 
Three unrelated people in the United States are selected at random.
This means that 
Find the probability that all three have type B+ blood.
This is P(X = 3).


The probability that all three have type B+ blood is 0.001728
It would be 60 dgrees since half of 1/3 is 1/6 and a circle is 360 degrees so do 360/6 to get 60 degrees.
Answer:

Step-by-step explanation:
Given: the probability that the movie rented by Nicole will be comedy is 52%.
To find: the probability that she rents NO MORE THAN two comedies
Solution:
Probability refers to chances of occurrence of some event.
Probability that the movie rented by Nicole will be comedy = 52% = 0.52
Probability that the movie rented by Nicole will not be comedy = 100% - 52% = 48% = 0.48
Probability that she rents NO MORE THAN two comedies = Probability that she rents no comedy movie + Probability that she rents one comedy movie + Probability that she rents two comedy movies
