Step-by-step explanation:
Answer:
63
Step-by-step explanation:
Given that;
The bag has two red marbles, n(red) =2
three green ones marbles, n(green) = 3
one lavender one marbles, n(lavender) = 1
two yellows marbles, n(yellow ) = 2
two orange marbles. n(orange) = 2
number of non green marbles = 2+1+2+2 = 7
The objective is to find out how many sets of four marbles include exactly two green marbles
Since sets of four marbles contain exactly two green marbles, then N(select 2 from 3 marbles and 2 from 7 marbles)
= ![^3C_2 \times ^{7}C _2](https://tex.z-dn.net/?f=%5E3C_2%20%5Ctimes%20%5E%7B7%7DC%20_2)
= ![\dfrac{3!}{2!(3-2)!} \times \dfrac{7!}{2!(7-2)!}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%21%7D%7B2%21%283-2%29%21%7D%20%20%5Ctimes%20%5Cdfrac%7B7%21%7D%7B2%21%287-2%29%21%7D)
= ![\dfrac{3*2!}{2!} \times \dfrac{7*6*5!}{2!(5)!}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%2A2%21%7D%7B2%21%7D%20%20%5Ctimes%20%5Cdfrac%7B7%2A6%2A5%21%7D%7B2%21%285%29%21%7D)
= ![3 \times 7\times 3](https://tex.z-dn.net/?f=3%20%20%5Ctimes%207%5Ctimes%203)
= 63
