Question

A jar contains 16 black balls,13 blue balls and 2 red balls in a bag. A ball is drawn in random. Find the probability of drawing a black ball? Find the probability of drawing a blue ball? Find the probability of not drawing a red ball?

Answer 1

black: 16/31 blue: 13/31 red 2/31

Answer 2

16 black, 13 blue, 2 red

16+13+2 = 31 total

16/31 is the probability of picking black

13/31 is the probability of picking blue

2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)
