P(1) = 0.7
P(2) = 0.2 assume she is 30
P(3) = 0.05
P(4) = 0.0001
P(5) = 0.001
P(6) = 0.01
P(7) = 0.001
P(8) = 0.001
P(9) = 0.01
assume all condition are independent, the probablity that she found a person is
7*10E_19
assume there are 8*10E8 man out there,she had to wait 10E11 years to find one,
some of the condition are also exclusive to each other,
The probability that she could live 10E11 years is almost zero
