Question

find the probability of selecting 2 green balls out of 4 green and 3 red balls

Answer 1

Answer:

1/2 or 2/7

Step-by-step explanation:

1/2 because: there are 4 green balls and the probability that 2 balls will be green or from the green balls is 2 out of 4 balls and therefore 1/2 or 50/50.

2/7 because: the probability that the 2 balls out of the 7 balls (3+4) will be green is 2 out of 7 and therefore 2/7
