Question

Help!
The sample space of an experiment is
{A, B, C},
where P(A) + P(B) = 0.71, P(B) + P(C) = 0.44. Find P(A), P(B), and P(C).

Answer 1

P(A)+P(B)+P(C)+P(B)=0.71+0.44=1.15
1+P(B)=1.15
P(B)=1.15-1=0.15
Now you can find P(A) and P(C)

Answer 2

Where did you get the 1 from?

Answer 3

total probability=1
\[P(A)+P(B)+P(C)=1\]

Answer 4

Got it =) Thank You
