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 like 4,9….is

(a) `1/45`

(b) `2/15`

(c) `4/45`

(d) `1/9`







(D) `1/9`
Explanation:
Total Numbers of Cards = 50 - 6 + 1

= 45 (Total Numbers of Outcomes)

Perfect Numbers are (between 6 - 50) = 4, 9, 16, 25, 36, 49, 64, 81, 100

Number of Perfect Square (between 6 - 50)= 5

Thus, P ( Getting a Perfect Squares ) = `"Numbers of Perfect Squares"/"Total Numberes"`

= `5/45`

= `1/9`
