Consider a collection of envelopes consisting of 3 red envelopes​, 1 blue envelope​, 2 green envelopes​, and 3 yellow envelopes. If two envelopes are selected at​ random, with​ replacement, determine the probability that at least one envelope is a red envelope.

The probability that at least one of the envelopes is red is 1/9.

Step-by-step explanation:

There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9.

answer: add the !

step-by-step explanation: then we will answer

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
