Probability that both balls are drawn from the box b = 7/16
Step-by-step explanation:
A box contains 2 white 3 red and 2 black balls
Total Balls = 7
Probability of one white & 1 Red from box A
= (2/7)(3/6) + (3/7)(2/6)
= 12/42
= 2/7
B box contains 4 white 2 red and 3 black balls
Total Balls = 9
Probability of one white & 1 Red from Box B
= (4/9)(2/8) + (2/9)(4/8)
= 16/72
= 2/9
probability that both balls are drawn from the box b = (2/9)/(2/9 + 2/7)
= (2/9)/((14 + 18)/63)
= 2 * 7 / 32
= 7 /16
probability that both balls are drawn from the box b = 7/16
