Answer:
The probability that more than a third of the buyers would prefer brown is 0.8491.
Step-by-step explanation:
This is binomial problem with n=15 and p=0.50.
The binomial formula of probaility is:
P(X=x)=
More than a third of the buyers: 15÷3=5
We have to find P(x>5).
P(x>5) = 1 - P(x≤5) = 1 - P(x=0) - P(x=1) - P(x=2) - P(x=3) - P(x=4) - P(x=5)
P(x=0)=
=0.00003
P(x=1)=
=0.00046
P(x=2)=
=0.00320
P(x=3)=
=0.01389
P(x=4)=
=0.04165
P(x=5)=
=0.09164
P(x>5) = 1 - P(x≤5)= 1- 0.00003 - 0.00046 - 0.00320 - 0.01389 - 0.04165 - 0.09164 = 0.8491
Answer: the answer is D

Answer:
The answer is B
Step-by-step explanation:
You need to graph the equation from the left of equality sign which is y=x*1/6 and the other is -2x+5
The first has a point (0,0) and other point could be (6,1) from there you can have your graph
The second has one point in (2.5, 0) and (0,5)
