Consider a collection of envelopes consisting of 3 red envelopes, 3 blue envelopes, 1 green envelope, and 3 yellow envelopes. if three envelopes are selected at random, without replacement, determine the probability that at least one envelope is a red envelope. the probability that at least one envelope is red is

Our required probability is

Step-by-step explanation:

Since we have given that

Number of red envelopes = 3

Number of blue envelopes = 3

Number of green envelopes = 1

We need to select 3 envelopes in such a way that at least one envelope is a red.

So, it becomes,

Hence, our required probability is

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer
