Question

A deck of cards contains red cards numbered 1,2,3,4,5, blue cards numbered 1,2,3,4,5,6,7,8 and green cards numbered 1,2,3,4,5,6,7,8,9,10. If a single card is picked at random, what is the probability that the card is green?

Give your answer as a fraction.

Answer 1

There are 23 cards in total and only 10 green cards. So the probability of drawing a green card would be 10/23
