n(a)
n(b)

THANK YOU ALL AGAIN FOR ALL OF YOUR HELP!
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
P(a)=40/(30+10+70)=4/11
P(b)=80/110=8/11
P(a|b)=10/80=1/8 Note: The "|" mark is on most computer keyboards. On mine it is above the "\" next to the square and curly brackets.
P(b|a)=10/40=1/4
I am not familiar with what n(a) and n(b) mean.
