Assume that 1/3 of all twins are identical twins. You learn that Miranda is expecting twins, but you have no other information. a. Find the probability that Miranda will have two girls. b. You learn that Miranda gave birth to two girls. What is the probability that the girls are identical twins? Explain any assumptions you make.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

a. Find the
b. You learn that Miranda gave birth to two girls. What is the probability that the girls are identical twins?
Explain any assumptions you make.
(a)
Consider that 1/3 of all the twins are identical twins. Then, "M" is expecting the twins.
Consider I is the identical twins, M is both are male and F is both are female and X is one twin male and the other female.
Then, the probability of getting non identical twins is,
1-1/3=2/3
The probability that "M" will have two girls is,
P(F)=
