P(MF)+P(MU)+P(MN) = 100
P(NF)+P(NU)+P(NN) = 100
P(MU)+P(MN)+P(NU)+P(NN)=40
implies that
P(MF) + P(NF) - P(MF and NF) = 60
40+30-P(MF and NF) = 60
P(MF and NF) = 10
SUFFICIENT
P(MU and NU)=10
With this info we can only get how many candidates did not respond unfavouravle for both candidates. But we need Not sure info also to calculate only favotrable.
INSUFFICIENT.
pick A
