A die is thrown 100 times and following observations were recorded:
Outcomes | 1 | 2 | 3 | 4 | 5 | 6 |
Frequency | 12 | 18 | 14 | 26 | 14 | 16 |
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)
