Answer:
Step-by-step explanation:
There are 12 E's out of 100 tiles.
Tiles are not replaced.
The probability of each of first 4 E's is:
- The first E ⇒ P(E) = 12/100 = 3/25
- The second E ⇒ P(E) = 11/99 = 1/9
- The third E ⇒ P(E) = 10/98 = 5/49
- The fourth E ⇒ P(E) = 9/97
The probability of 4 E's is:
- P(4 E's) = 3/25*1/9*5/49*9/97 = 3 / (5*49*97) = 3 / 23765
