The number of inches of rain that fell during the month of April was recorded over time. The number of years the total fell in each category is recorded below. Fill in a probability distribution for this data in the third line of this chart. a. inches of rain x<1 1<x<2 2<x<3 3<x<4 x>4 number of years 4 13 21 10 2 probability ? ? ? ? ? b. What is the probability that the number of inches of rain for April is less than 2 inches? c. What is the probability that the number of inches of rain for April is 3 or more inches?
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.
The number of inches of rain that fell during the month of April was recorded over time. The number of years the total fell in each category is recorded below. Fill in a
| inches of rain | x<1 | 1<x<2 | 2<x<3 | 3<x<4 | x>4 |
| number of years | 4 | 13 | 21 | 10 | 2 |
| probability | ? | ? | ? | ? | ? |
b. What is the probability that the number of inches of rain for April is less than 2 inches?
c. What is the probability that the number of inches of rain for April is 3 or more inches?
