Answer:
![\frac{10}{21}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B21%7D)
Step-by-step explanation:
Total number of balls = ![(2 + 3 + 2) = 7](https://tex.z-dn.net/?f=%282%20%2B%203%20%2B%202%29%20%3D%207)
Let S be the sample space.
Then, n(S) = Number of ways of drawing 2 balls out of 7
= ⁷ C₂
= ![\frac{(7*6)}{(2*1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%287%2A6%29%7D%7B%282%2A1%29%7D)
=21
Let E = Event of drawing 2 balls, none of which is blue.
∴n(E)= Number of ways of drawing 2 balls out of (2 + 3) balls.
= ⁵ C₂
= ![\frac{(5*4)}{(2*1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%285%2A4%29%7D%7B%282%2A1%29%7D)
= 10
∴ P (E) = ![\frac{n(E)}{n(S)} =\frac{10}{21}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%28E%29%7D%7Bn%28S%29%7D%20%3D%5Cfrac%7B10%7D%7B21%7D)
Answer:
![y^2 + 2y + 80](https://tex.z-dn.net/?f=y%5E2%20%2B%202y%20%2B%2080)
Step-by-step explanation:
![6y^2 + 2y + 5 - (5y^2 - 64 - 11)](https://tex.z-dn.net/?f=6y%5E2%20%2B%202y%20%2B%205%20-%20%285y%5E2%20-%2064%20-%2011%29)
[pay attention to the signs :)
![y^2 + 2y + 80](https://tex.z-dn.net/?f=y%5E2%20%2B%202y%20%2B%2080)
