Stuck on a problem in statistics about probability frequency distribution? This how to article will show you how to solve these probability problems in just a few easy steps. A probability frequency distribution is a way to show how often an event will happen. It also shows what the probability of each event occurring is. A frequency distribution table is usually used in probability and statistics to show probability frequency distribution. Frequency distribution tables can be created by hand, or you can use technology like Microsoft Excel to create the tables.
Sample question: In a sample of 43 students, 15 had brown hair, 10 had black hair, 16 had blond hair, and 2 had red hair. Use a frequency distribution table to find the probability a person has neither red nor blond hair.
Step 1: Make a table.
Step 2:Add up the totals.
In the sample question we’re asked for the odds a person will not have blond or red hair. In other words, we want to know the probability of a person having black or brown hair.
Brown = 15/43 (15 out of 43 students have brown hair)
Black = 10/43 (10 out of 43 students have black hair)
15/43 + 10/43 = 25/43 (25 out of 43 students have either brown or black hair)
