Answer:
7/16
Step-by-step explanation:
1st bag
2 black balls, 1 white ball, and 1 red ball.
P(white) = white/total = 1/4
2nd bag
2 black balls, 1 white ball, and 1 red ball.
P(red) = 1/4
The events are independent, so multiply the probabilities
P(white 1st bag, red 2nd bag) = 1/4*1/4 =1/16
To find the probability of white or red we cannot double count both
P(white or red) = P(white) + P(red) - P(white , red)
=1/4 + 1/4 - 1/16
= 4/16 + 4/16 - 1/16
=7/16
