3. So far in a major league baseball player's career, he has gotten a hit in 30% of his at-bats. An announcer in the game claims that the player has a probability of 0.30 of getting a hit. Which of the following is the best interpretation of the probability? a. If the player has not had a hit in the last seven at-bats, he is more likely to get a hit in the next at-bat. b. In the next ten at-bats, the player will get 3 hits. As the player gets more and more at-bats, the number of hits the player gets out of the total number of at-bats will be get closer and closer to 30%. d. In a season where the player has 500 at-bats, he will get 150 hits.

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.

is due to make his next shot because of the law of averages.
b. When pick random integers from 1 to 10 on your calculator, it is just as likely to get the
sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 as it is to get 1, 1, 1, 1, 1, 1, 1, 1, 1, 1.
c. A family has had 5 children and each child was a boy. The next child they have is more

4. The teachers at a local high school were surveyed. Two of the variables recorded for the 150 teachers were
housing status and length of service. Housing status was recorded as owning or renting your residence, while
length of service was classified as a new teacher with less than 5 years of service or as an experienced
teacher with at least 5 years of service. The following table summarizes the responses. Based on the
responses, what is the probability that a randomly selected teacher from this school is a teacher who has less
than 5 years of teaching experience and who owns their own home?
