Answer:
24/121
Step-by-step explanation:
The probability of an event happening is the ratio of the number of possible outcome to the number of total outcome.
The probability of not getting green then green
= rg or bg
Where r is the probability of getting red, g is the probability of green and b is the probability of blue.
= 4/11 * 3/11 + 4/11 * 3/11
= 12/121 + 12/121
= 24/121
