A die is thrown 100 times and following observations were recorded:


If a die is thrown at random, find the probability of getting

(i) a number less than 3? (ii) a number greater than 4 (iii) an even number

Total number of outcomes : 100

(i) Chances of getting a number less than 3 on the die = 2 (They are 1,2)

Its frequency is: 12+18 = 30

Probability P() =

Probability of getting a number less than 3 on die P(less than 3)

=

(ii) Chances of getting a even number on the die = 3 (They are 2,4,6)

Frequency : 18+26+16 = 60

Probability P() =

Probability of getting a composite number on die the P(even number)

(iii) Chances of getting a number greater than 4 on the die = 2 (They are 5,6)

Frequence : 14+16 = 30

Probability P() =

Probability of getting a number not less than 4 on die P(greater than 4)
