A box contains cards numbered 6 to 50. A card is drawn at random from the box. The probability that the drawn card has a number which is a perfect square is
Total numbers of elementary events are: 50 – 5 = 45 number 6 is included
Let E be the event of drawing a perfect square
The favourable outcomes are: 9, 16, 25, 36, 49
Numbers of favourable outcomes = 5
P (E) = 5/45 = 1/9
