Question

A jar contains 8 large red marbles, 5 small red marbles, 9 large blue marbles, and 7 small blue marbles. If a marble is chosen at random, which of the conditional probabilities is larger, P(blue|small) or P(small|blue)?

Answer 1

Answer:

P(blue|small) > P(small|blue)

Step-by-step explanation:

P(blue|small):  7 / (5 + 7) = 7 / 12

P(small|blue): 7 / ( 9 + 7) = 7 / 16

7 / 12 > 7 / 16
