Question

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/20 for yellow, 1/10 for green, 1/15 for red, and 1/25 for purple. What is the probability of pulling a purple or green card, written as a reduced fraction?

Answer 1

Probability helps us to know the chances of an event occurring. The probability of pulling a purple or green card is 7/50.

What is Probability?

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

The probabilities of different color cards being pulled are 1/20 for yellow, 1/10 for green, 1/15 for red, and 1/25 for purple. Therefore, the probability of pulling a purple or green card is,

Probability = 1/25 + 1/10

                  = (10 + 25) /250

                  = 35/250

                  = 7/50

Hence, the probability of pulling a purple or green card is 7/50.
