In a box, there are 3 fair coins, 2 special coins with heads on both sides and 5 special coins with tails on both sides. A coin is randomly selected and flipped. (a) If a head comes up, what is the probability that the selected coin is a special coin with heads on both sides? (b) When the same coin is flipped again, if a head still comes up, what is the probability that the selected coin is a special coin with heads on both sides?
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.
In a box, there are 3 fair coins, 2 special coins with heads on both sides and 5 special coins
with tails on both sides. A coin is randomly selected and flipped.
(a) If a head comes up, what is the probability that the selected coin is a special
coin with heads on both sides?
(b) When the same coin is flipped again, if a head still comes up, what is the
probability that the selected coin is a special coin with heads on both sides?
