probability frequency distribution
Tip: If you have a large number of items, use tally marks to help you find the total.
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. Note that you’re told in the question there are 43 students in the class.
Brown = 15/43 (15 out of 43 students have brown hair).
Black = 10/43 (10 out of 43 students have black hair).
Add these together to get the total number of students who have brown or black hair.
15/43 + 10/43 = 25/43 (25 out of 43 students have either brown or black hair).
