Suppose that you are offered the following "deal." You roll a six sided die. If you roll a 6, you win $12. If you roll a 2, 3, 4 or 5, you win $5. Otherwise, you pay $4. D. Based on the expected value, should you play this game?
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.
Suppose that you are offered the following "deal." You roll a six sided die. If you roll a 6, you win $12. If you roll a 2, 3, 4 or 5, you win $5. Otherwise, you pay $4.
D. Based on the
- Yes, because you can win $12.00 which is greater than the $4.00 that you can lose.
- Yes, since the expected value is 0, you would be very likely to come very close to breaking even if you played many games, so you might as well have fun at no cost.
- Yes, since the expected value is positive, you would be very likely to come home with more money if you played many games.
- No, this is a gambling game and it is always a bad idea to gamble.
- No, since the expected value is negative, you would be very likely to come home with less money if you played many games.
