P(baseball)

Answer to Problem 21P

  $\frac{11}{60}$

Explanation of Solution

Given:

One hundred twenty randomly selected students at Roosevelt High School were asked to name their favourite sport.The results are :

  

Formula Used :

  $\text{P(E) = }\frac{\text{number of favourable outcomes of E}}{\text{total number of outcomes}}$

Calculation:

Number of responses for basebal = 22

Total number of students = 120

  $P(baseball)=\frac{\text{number of responses for baseball}}{\text{total number of students}}=\frac{22}{120}=\frac{11}{60}$
