Question

Mr. Stewart has 26 students in his class. Ten of his students are girls. If Mr. Stewart writes each student's name on a small strip of paper, puts all the paper strips into a hat, and then pulls out one strip without looking, what is the probability that he will pull out a boy's name?

Answer 1

8/13

Explanation:

Step 1 : Write all the data

Total number of students = 26

Number of girls in class = 10

Number of boys in class = 26-10 = 16

Step 2 : Find the probability

Probability of pulling out a boy's name = number of boys in class

Total number of students in class

= 16/26

Simplify :

16/26 = 8/13
