If a group of five women is participating in a 400 meter race in preparation for the Olympics, then what is the probability that either Jenny or Sally win the race?

1/5
14/15
2/5
1/2
3/5

P(j) = 1/5
P(s)=1/4

p ( j or s ) = 1/5 +1/4 = 9/20

what's going wrong :(

1/5 + 1/5 = 2/5 ?

Since they cannot both win, (PnB) = 0, and P(AuB) = P(A)+P(B)+0
