Answer :

Probability of red or green card = 3/5

Explanation:

Number of red cards = 3

Number of blue cards = 6

Number of green cards = 6

Total number of cards = 6 + 6 + 3 = 15

Probability of red or green card = Probability of red card + Probability of green card

Probability of red card = number of red cards/total number of cards

Probability of red card = 3/15

Probability of green card = number of green cards/total number of cards

Probability of green card = 6/15

Probability of red or green card = 3/15 + 6/15

Probability of red or green card = 9/15

In simplest term:

Probability of red or green card = 3/5
