Question

at the start of a scrabble game, your turn over the 100 letter tiles so you cannot see them. there are 4 S's and 2 blacks among the tiles. if you pick up one tile at the random, what is the probability you will not get an S nor a blank

Answer 1

the probability of not getting an s or a blank is 94/100.

this is because there are 94 chances to get something other than those 6 tiles.
