P(a) =0.20 p(b) = 0.25 p(a and b) = 0.10. what is p(b/a)?
a. 0.25
b. 0.40
c. 0.50
d. 0.05

Final answer is

Step-by-step explanation:

Given that P(A) =0.20

P(B) = 0.25

P(A and B) = 0.10.

Now we need to find about what is the value of P(B/A).

P(A and B) = P(A) * P(B/A)

Plug the given values into above formula:

Hence final answer is

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
