Answer:
x=-1
Step-by-step explanation:
given -2=0
=2
x+3=+2
x=-1, also, x+3=-2
x=-2-3=-5
hence x=-1 , -5 answer

Step-by-step explanation:
Given that a researcher wishes to conduct a study of the color preferences of new car buyers.
Suppose that 50% of this population prefers the color red
15 buyers are randomly selected
Let X be the no of buyers who prefer red.
X has exactly two outcomes red or non red.
Also each buyer is independent of the other
Hence X is binomial with p = 0.5 and n = 15
Required prob =The probability that exactly three-fifths of the buyers would prefer red
= P(X=9)
=
