A 5-card hand is dealt from a standard 52-card deck. If the 5-card hand contains at least one ace, you win $11; otherwise, you lose $1. What is the expected value of the game? dollars. The expected value of the game is (Type an integer or a decimal rounded to two decimal places.)
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 deck of 52 cards we have 4 ace cards.
The probability of no ace card is computed as,
Thus,
P(at least one ace card) = 1- P(No ace card)
= 1-0.658842
= 0.341158.
