19. The probability of winning a raffle if 500 tickets are sold and you buy 5 of them is 5/500 or 1/100. you would only have a 1 percent chance that you would get a winning raffle.
Every random pick out of 25, 15 times it will be a girl.
Because there are two Ms, two As, and two Ts, there are 8 DIFFERENT letters.
My own question:
What is the probability that a letter chosen at random is in the word . . .
Well scince there are ...
- 3 Ss - 3 Ls
- 2 Us - 7 Is
- 2 Ps - 1 F
- 2 Es - 1 G
- 2 Rs - 1 T
- 3 Cs - 1 X
- 3 As - 1 D
- 2 Os
... and only 26 letters in the alphabet,
the probability of a letter being chosen
at random is this word is 15/26.
There are only 15 DIFFERENT letters.
