Question

a die is rolled once find the probability of getting [i} an even number
[ii] a multiple of 3 [iii] not a multiple of 3

Answer 1

Answer:

Step-by-step explanation:

Sample set of this event is = {1,2,3,4,5,6}

1)sample set of the event(getting an even number) = {2,4,6}

  probability of getting an even number = 3/6 = 1/2

2)sample set of the event(getting a multiple of 3) = {3,6}

  probability of getting a multiple of 3 = 2/6 = 1/3

3) since probability of getting a multiple of 3 is 1/3

  therefore,probability of getting a number which is not a multiple of 3 is

  (1 - probability of getting a multiple of 3) = (1-1/3) = 2/3
