Question 184492: A letter is taken at random from the letters of the word 'statistics' and another letter is taken at random from the letters of the word 'assistant'. what is the probability that they are the same letter? Answer by Jasmine=](1) (Show Source):
You can put this solution on YOUR website! Statistics has 10 letters in them. Assistant has 9 letters in them. Add them up and you get 19. (19 will be your denominator)
In Statistics there are 3 letter T's. In assistant there are 2 letter T's.Add them up and it equals 5,so there are 5 T's out of 19 letters. Statistics has 3 letter S's and Assistant has 3. Add them up and you get 6. So there are 6 S's out 19 letters. In statistic you have 1 letter A and in Asistant you have 2. Add them up and you get 3.So there are 3 letter A's out of 19 letters. Statistics has 2 letter i's and Assistant has 1. Add them up and you get 3. so There are 3 i's out of 19 letters . NEXT- You have to put them in fractions.
5/19+5/19+3/19+3/19=17/19 JUST ADD STRAIGH ACCROSS. 5+5+3+3=16 The probability of getting the same letters is 16 out of 19.
