A jar contains 10 green, 6 white, and 11 brown marbles. A marble is drawn at random.
P(brown or white)
I think 17/27
A number from 16 to 28 is drawn at random.
P(an even number)
I think 7/13
10+6+11=27 brown+white=17 so 17/27 correct
16,18,20,22,24,26,28
so 7/?
16,17,18,19,20,21,22,23,24,25,26,27,28 so ?/13 ---- 7/13
Correct
