Given that P(B|A)=0.88 and P(A)=0.46, what is P(B AND A)? Round to three decimal places.

Work Shown:

The notation P(B|A) has a vertical line separating the B and A

Given values

P(B|A) = P(B and A)/P(A) ... conditional probability formula

P(B and A) = P(B|A)*P(A) ... solve for P(B and A)

P(B and A) = 0.88*0.46 ... plug in given values

P(B and A) = 0.4048

P(B and A) = 0.405 rounding to three decimal places

This is the same as P(A and B).

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
