Question

I need h e l p !!!!!!!!!!!!!!!!

Answer 1

• 3/ 23765

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
