Question 1116373: Consider a collection of envelopes consisting of 2 red envelopes , 1 blue envelope, 1 green envelope, and 22 yellow envelopes. If two envelopes are selected at random, with replacement, determine the probability that both are blue envelopes. Answer by ikleyn(52781) (Show Source):
2 + 1 + 1 + 22 = 26 is the total number of envelopes.
The probability to select the (unique) blue of the total 26 envelopes is at the first selection,
and it is the same at the second selection after replacement.
So the answer is .
