Question

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/5 for black, 1/25 for green, 1/15 for purple, and 1/20 for blue. What is the probability of pulling a purple or blue card, written as a reduced fraction?

Answer 1

7/60

Explanation:

Blue or purple = probability of blue + probability of purple

1/15 + 1/20 = 4/60 + 3/60 = 7/60

Hope this helps :)

Have a nice day!
