Jack rolls a six-sided number cube then chooses one card from a deck of three cards numbered 2 through 4. What is the probability that the number cube and the card have the same number?
There are 6 possible outcomes when rolling a six-sided number cube and 3 possible outcomes when choosing a card numbered 2 through 4.
The numbers that are common between the number cube and the card are 2, 3, and 4.
Therefore, the probability that the number cube and the card have the same number is 3 common outcomes / (6 possible outcomes x 3 possible outcomes) = 3/18 = 1/6.
