If two dice are rolled one time, find the probability of getting these results: a) A sum less than 9 b) A sum greater than or equal to 10 c) A 3 on one die or on both dice. C. If one card is drawn from a deck, find the probability of getting these results: a) An ace b) A heart c) A 6 of spades d) A 10 or a jack e) A card whose face values less than 7 (Count aces as 1.) D. Human blood is grouped into four types. The percentages of Americans with each type are listed below. O 43% A 40% B 12% AB 5% Choose one American at random. Find the probability that this person a) Has type B blood b) Has type AB or O blood c) Does not have type O blood E. The population of Hawaii is 22.7% white, 1.5% African-American, 37.7% Asian, 0.2% Native American/Alaskan, 9.46% Native Hawaiian/Pacific Islander, 8.9% Hispanic, 19.4% two or more races, and 0.14% some other.

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.
