Next may, on ornithologist intends to trap one male Pickleoo and one female Pickleoo. The mass M
of the male Pickleoo may be regarded as being a normal random variable with mean 116g and
standard deviation 16g. The mass F of the female Pickleoo may be regarded as being independent
of M and as being a normal random variable with mean 106g and standard deviation 12g.

Suppose that one of the two trapped birds escapes. Assuming that the remaining birds be equally
likely to be the male or the female, determine the probability that it’s mass will be more than
118g.
