Given Total numbers = 40
Formula used P(E) =
| Numberoffavourableoutcomes |
| Totalnumberofoutcomes |
Calculation Let E is an event of drawing a card multiple of 3 or 4
Number of favourable outcomes = 20 i.e(102, 104, 105, 108, 111, 112, 114, 116, 117, 120, 123, 124, 126, 128, 129, 132, 135, 136 ,138 and 140)
P(E) = 20/40 = 1/2
