Answer:
<h2><em><u>2a</u></em></h2>
Step-by-step explanation:
(a+b-c)-(b-a-c)

Answer:
Step-by-step explanation:
Urn has 3 green and 4 yellow
we choose 2 balls randomly
so samples space for this selection is
![\left [ \left ( Y,G\right ),\left ( G,Y\right ),\left ( G,G\right ),\left ( Y,Y\right )\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%20%5Cleft%20%28%20Y%2CG%5Cright%20%29%2C%5Cleft%20%28%20G%2CY%5Cright%20%29%2C%5Cleft%20%28%20G%2CG%5Cright%20%29%2C%5Cleft%20%28%20Y%2CY%5Cright%20%29%5Cright%20%5D)
Event A is choosing differently colored ball form sample space
P(A)=Probability of event (G,Y)+Probability of event (Y,G)


8n - 7
because from 8n, 7 is subtracted
(x + 4)^4 = x^4 + 16x^3 + 96x^2 + 256x + 256
