Question

Claire has 8 cards: 4 red cards and 4 blue cards. She draws 3 cards from the set at random. What is the probability that all 3 cards are red?

Answer 1

4/56 simplified is 1/14

Explanation:

nCr(8,3) = 56

4 (the number of red cards there are) / 56 = 1/14

Answer 2

Answer: 1/14 assuming cards are nut returned back in deck

Step-by-step explanation: first is red P(1. R) = 4/8 = 1/2

Second red P(2. R) = 3/7 and P(3. R) = 2/6 = 1/3.

Multiply probabilities , you get 1/14
