A survey from Teenage Research Unlimited found that 40% of teenage consumers receive their spending money from part-time jobs. If 5 teenagers are selected at random: Find the probability that at least 3 of them will have part-time jobs. Find the probability that no more than 4 will have part-time jobs. Find the probability that less than 5 but greater than 3 will have part-time jobs.
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 survey from Teenage Research Unlimited found that 40% of teenage consumers receive their spending money from part-time jobs. If 5 teenagers are selected at random:
- Find the
probability that at least 3 of them will have part-time jobs. - Find the probability that no more than 4 will have part-time jobs.
- Find the probability that less than 5 but greater than 3 will have part-time jobs.
