Aand b are independent events. p(a) = 0.50 and p(b) = 0.20 what is p(a and b)

P ( a and b ) =  0.1

Step-by-step explanation:

Given : P(a) = 0.50 and  p(b) = 0.20.

To find  : what is p(a and b).

Solution : We have given that P(a) = 0.50 and  p(b) = 0.20.

P( a and b ) = p(a) × p(b) .

Then P ( a and b ) =  0.50 × 0.20 .

P ( a and b ) =  0.1 = .

Therefore, P ( a and b ) =  0.1
