Answer:
Probality (Black Balls ) = 1/5
Step-by-step explanation:
Number of black balls in bag 1 = 3
Number of white balls in bag 1 = 2
Total balls = 3+2 = 5
Probality ( Black balls in bag 1) = 3/5
Number of black balls in bag 2 = 2
Number of white balls in bag 2 = 4
Total balls = 2+ 4= 6
Probality ( Black balls in bag 2) = 2/6= 1/3
Probality ( black balls in bag 1 & bag 2)
= 3/5 * 1/3
= 1/5
