Question

There are 140 preschoolers enrolled in a gymnastics class. The ages and numbers of preschoolers enrolled are shown in the table. Preschooler Gymnastics Enrollment Age (years) Number of Preschoolers 2 36 3 44 4 60 What is the probability that one preschooler selected at random is 3 years old? ​

Answer 1

The probability of randomly selecting a 3 years old is 0.314

Using the parameters given for our Calculation;

• Number of 3 years old preschooler = 44
• Total number of preschoolers = 140

The probability of an event is calculated thus ;

• Number of favorable outcomes/ Number of total possible outcomes

Now we have ;

P(3 years) = 44/140

= 0.314

Hence, the probability is 0.314
