One ticket is drawn at random from a big containing tickets numbered 1 to 40. The probability that the selected ticket has a number, which is a multiple of 7, is
Total numbers of elementary events are: 40
Let E be the event of getting multiple of 7
Favourable outcomes are: 7, 14, 21, 28, 35
Number of favourable outcome = 5
P(E) = 5/40 = 1/8
