To solve for b, you need to isolate/get the variable "b" by itself in the equation:

A = h(a + b) Divide h on both sides

$\frac{A}{h}=\frac{h(a +b)}{h}$

$\frac{A}{h} =a + b$ Subtract a on both sides to get "b" by itself

$\frac{A}{h}-a=a-a+b$

$\frac{A}{h} -a=b$

Answer: $\frac{15}{56}$

Step-by-step explanation:

We have to select george but not nina with two other people

No. of ways selecting 2 two people knowing Geroge will be the third one is

$^6C_2$ (beacuse we have to exclude Nina)

And total no of ways of selecting 3 people out of 8 people is $^8C_3$

Therefore the required Probability is $\frac{^6C_{2}}{^8C_{3}}$

= $\frac{15}{56}$
