Q8 of 24 Page 97

A die is rolled 500 times. The following table shows that the outcomes of the die.


Find the probability of getting an outcome (i) less than 4


(ii) less than 2


(iii) greater than 2 (iv) getting 6 (v) not getting 6.

(i) Outcomes less than 4 includes the outcomes of getting 3, 2, 1.


Total times = 500


Favorable outcomes out of 500 is 80 + 75 + 90 (favorable outcomes of 1,2 and 3 respectively)



(ii) Outcomes less than 2 includes the outcomes of getting 1.


Total times = 500


Favorable outcomes out of 500 is 80 (favorable outcomes of getting a 1)



(iii) Outcomes greater than 2 includes the outcomes of getting 3, 4, 5, 6.


Total times = 500


Favorable outcomes out of 500 is 90,75,85,90 (favorable outcomes of getting 3,4,5 and 6 respectively)



(iv) Outcomes of getting a 6.


Total times = 500


Favorable outcomes out of 500 is 95 (favorable outcomes of getting 6)



(v) Outcomes not getting a 6 includes the outcomes of getting 1,2,3,4,5.


Total times = 500


Favorable outcomes out of 500 is 80 + 75 + 90 + 75 + 90 (favorable outcomes of 1,2 and 3 respectively)
