Question

A dice is thrown 120 times and the observations are noted. (Mention the formula) OUTCOME : 1 , 2 , 3 , 4 , 5 , 6 FREQUENCY: 21 , 19 , 14 , 18 , 25 , 23\ a)6 b) Number less than 2 c) An even number

Answer 1

Answer:

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.
