Solution

Total number of trials = 100
Number of times 3 is obtained = 18
Number of times 6 is obtained = 9
Number of times 4 is obtained = 15
Number of times 1 is obtained = 21

(i) Probability of getting a 3=Number of times 3 is obtainedTotal number of trials =18100=950(ii) Probability of getting a 6=Number of times 6 is obtainedTotal number of trials =9100(iii) Probability of getting a 4=Number of times 4 is obtainedTotal number of trials =15100=320(iv) Probability of getting a 1=Number of times 1 is obtainedTotal number of trials =21100
