QUESTION 12 Sales records of a hobby shop showed the following number of radio-controlled trucks sold weekly for each of the last 50 weeks. What is the probability of selling between 1 and 3 (inclusive) trucks in any given week? Number of Trucks Sold Number of Weeks 20 15 10 4. 1 O P(1,2,3) = 15/50 = 0.30 O P(1,2,3) = 4/50 + 1/50 = 0.10 O P(1,2,3) = 10/50 = 0.20 O P(1,2,3) = 15/50 + 10/50 + 4/50 = 0.58

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.

O P(1,2,3} = 15/50 = 0.30
O P(1,2,3} = 4/50 + 1/50 = 0.10
O P(1,2,3} = 10/50 = 0.20
O P(1.2,3} = 15/50 + 10/50 + 4/50 = 0.58
