Answer:

The probability that the drawn card has a number which is a perfect square is (d)
(1)/(9).

Explanation:

A box contains cards numbered
6 to
50. So there are total
45 cards, which is the sample space.

Among these cards, the numbers which are a perfect square are
9,16,25,36,49. So, there are
5 perfect square number cards, whose probability we have to find.

Its probability is given by,


\begin{aligned}(Cards Present)/(Sample Space) &= (5)/(45) \\&=(1)/(9)\end{aligned}

So, option d is correct.
