Question

A dice is thrown 100 times and the outcomes are recorded as follows: Outcomes 1 2 3 4 5 6 Frequency 25 20 12 18 15 10 From the above given data evaluate the following probabilities : i) P(Even number) ii) P(Prime number)

Answer 1

Given,

Total number of trials = 100

Number of times “5” comes up = 18

Probability of getting 3 =  

Totalnumbersoftrails

Frequencyofgetting5

​  

 

=  

100

18

​  

 

= 0.18

So, If a die is thrown at random, probability of getting 5 is 0.18.
