Answer:

3 2-pt shots, 4 3-pt shots

Step-by-step explanation:

2x + 3y = 18

x + y = 7, so x = 7 - y

Substitute in for x

2(7 - y) + 3y = 18

14 - 2y + 3y = 18

14 + y = 18

y = 4

Now put 4 in for y to solve for x

2x + 3(4) = 18

2x + 12 = 18

2x = 6

x = 3

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
