A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t
Thepotemich [5.8K]

Answer:

The probability that exactly 12 buyers would prefer green

=0.00555

Step-by-step explanation:

We are given that

p=50%=50/100=0.50

n=14

We have to find the probability that exactly 12 buyers would prefer green.

q=1-p

q=1-0.50=0.50

Using binomial distribution formula

P(X=x)=nC_r p^r q^{n-r}

P(x=12)=14C_{12}(0.50)^{12}(0.50)^{14-12}

P(x=12)=14C_{12}(0.50)^{12}(0.50)^2

P(x=12)=14C_{12}(0.50)^{14}

P(x=12)=\frac{14!}{12!2!}(0.50)^{14}

P(x=12)=\frac{14\times 13\times 12!}{12!2\times 1}(0.50)^{14}

P(x=12)=91\cdot (0.50)^{14}

P(x=12)=0.00555

Hence, the probability that exactly 12 buyers would prefer green

=0.00555

In this relation we have two ordered pairs:
( 5, 7 ) and ( 5, 8 )
For x = 5 :  f ( x ) = 7 and also for x = 5,  f ( x ) = 8. This is not possible for a function.
Answer:
b ) No. The relation is not a function.
