A dice is thrown 20 times and the outcomes are noted as shown below :
Now a dice is thrown at random, find the probability of getting :
∵ Total number of outcomes = 20
(i) P (getting 3) = 4/20 = 1/5
(ii) A number less than 3 (1, 2) will appear = 2 + 3 = 5 times
∴ Probability = 5/20 = 1/4
(iii) A number greater than 3(4, 5, 6) will appear = 4 + 3 + 4 = 11 times
∴ Probability = 11/20
