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

How can you get 3/3 -1/6?

Answer:

5/6

Step-by-step explanation:

Addition or subtraction of fractions requires a common denominator. The value 3/3 can be multiplied by 2/2 to give 6/6, which has the same denominator as the other fraction.

$\dfrac{3}{3}-\dfrac{1}{6}=\dfrac{3\cdot2}{3\cdot2}-\dfrac{1}{6}\\\\=\dfrac{6}{6}-\dfrac{1}{6}=\dfrac{6-1}{6}=\boxed{\dfrac{5}{6}}$
