Question

You randomly choose one of the tiles. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.

The probability of choosing 5 and then 6 is...

Answer 1

To get a compound event, you multiply the chance of the first and the 2nd possibility. There are 7 tiles, and one 5. So there is an 1/7 chance for the 1st possibility. The second possibility is 1/6 because 7 - 1 = 6, and only one 6. So 1/7 times 1/6 = 1/42.
