Question

A bag has purple, pink and yellow marbles.

The probability of selecting a purple marble is 1/6
and the probability of selecting a pink marble is
3/4
Find the probability of selecting a yellow
marble.

Answer 1

1/12

Explanation:

P(yellow) + P(purple) + P(pink) = 1, because all probabilities have to add up to 1 (100%).

P(yellow) = 1 - P(purple) - P(pink)

= 1 - 1/6 - 3/4

= 1/12.

so, the probability of selecting a yellow marble is 1/12
