Could someone please check this for me :-). Thank-you
A box contains 22 red apples and 3 green apples. Three apples are selected at random one after the other without replacement.
What is the probability that exactly two of the three apples are red?
The way I'm trying to solve the problem is like this:
Possible combinations:
RRG
GRR
RGR
probability of red: 3/25
probability of green: 22/25
3/25 * 2/24 * 22/23 = 11/1150
22/25 * 3/24 * 2/23 = 11/1150
3/25 * 22/24 * 2/23 = 11/1150
So the answer would be (11/1150)*3 = 33/1150
Is this correct?
Nevermind!!
I just found out I switched around the probabilities for red and green apples, lol
thanks anyway:D
