This is a question about compound events:
The game of Scrabble includes 100 lettered tiles. 42 of the tiles represent vowels. If you select a tile, put it back, and select again, what is the probability of getting a vowel both times?
The probability of getting both (or all) events is obtained by multiplying the probability of the individual events.
The probability of getting a vowel one time is 42/100 = .42
I hope this helps. Thanks for asking.
