next may an ornithologist intends to trap one male cuckoo and one female cuckoo. The mass M of the male cuckoo may be regarded as being a normal random variable with mean 116g and standard deviation 16g. The mass F of the female cuckoo 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 bird will be equally to be the male or the female, determine the probability that it's mass will be more than 118g.

Show workings.
