a survey of college graduates, 61% reported that they entered a profession closely related to their college major. If 8 college graduates are randomly selected, use the binomial distribution to find the probability of each item. a) Getting exactly 3 (x=3) that entered a profession closely related to their major. b) Getting 3 or fewer (x≤3) that entered a profession closely related to their major. c) Getting at least one (x≥1) that entered a profession closely related to their major. d) Find the mean and standard deviation. e) Would it be unusual for all 8 to be in a profession closely related to their majo
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.

a) Getting exactly 3 (x=3) that entered a profession closely related to their major.
b) Getting 3 or fewer (x≤3) that entered a profession closely related to their major.
c) Getting at least one (x≥1) that entered a profession closely related to their major.
d) Find the mean and standard deviation.
e) Would it be unusual for all 8 to be in a profession closely related to their major?
