For a group of twins, pairwise concordance is defined as C/(C+D), where C is the number of concordant pairs and D is the number of discordant pairs. In a study of 50 MZ twin pairs: There are 2 pairs for which both twins have consumed mushrooms.
There are 38 pairs for which neither twin has consumed mushrooms.
There are 10 pairs for which only one of the twins has consumed mushrooms.

Required:
