Question 870446
1000 Ind: 800S, 50F, 150A
pull out one listing at random to contact
a) P(S) = 800/1000 = 4/5 = .8  0r 80%
b) P(A) = 150/1000 = 15/100 = 3/20 = .15  0r 15%
c) P(F 0r A)= 50/1000 + 3/20 = 1/20 + 3/20 = 4/20 = 1/5  0r 20%
d) P(S + F) = 850/1000 = 85/100 = 17/20 = .85  0r  85%
the more of the entire population the classification is...the larger the %
