Two events are said to be mutually exclusive if: they both have at least one outcome in common. they both contain the same outcomes they do not contain any outcomes in common. one event contains all of the outcomes that are not contained in the other event. Previous Next In the game of Scrabble, each player begins by drawing 7 tiles from a bag initially containing 100 tiles. There are 42 vowels, 56 consonants, and 2 blank tiles in the bag. Suppose you are playing Scrabble and get to go first. If you randomly select 7 tiles from the bag, what's the probability that all of them are vowels? 0.171 O 0.0017 O 0.343 O 0.13 O 0.159 Suppose you and 9 of your friends are going out to dinner (for a total of 10 people).
