Question

One ticket is drawn at random from a box containing 30 tickets numbered 1 to 30. Represent the sample space and also write the sample space of drawing a ticket containing number which is a multiple of 4.

Answer 1

The sample space S = {1, 2, 3, 4, 5,…., 30}

Let E be the event of getting a ticket whose number is a multiple of 4. 

∴ E = {4, 8, 12, 16, 20, 24, 28}.
