Probability helps us to know the chances of an event occurring. The probability of pulling a green or red card is 9 / 100.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
P =  
The probabilities of different color cards being pulled are 1/25 for red, 1/20 for green, 1/15 for purple, and 1/10 for black Therefore, the probability of pulling  a green or red card is,
Probability = 1/20 + 1/25
                  = (5 + 4) /100
                  = 9 / 100
Hence, the probability of pulling a green or red card is  9 / 100.
