The system of equations graphed below has how many solutions?

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
