There are 105 lettered tiles in a board game. You choose the tiles shown. How many of the 105 tiles would you expect to be vowels?
the tiles are: R, A, M, E, I, L, B
Assuming that all samples of 7 tiles have the same ratio of vowels / consonants....
Out of the 7 tiles, 3 are vowels
So....the number of tiles expected to be vowels out of 105 = (3/7) (105) = 45
