The possible perfect squares which can be obtained are 1 and 4 . Required probability = probability (obtain- ing 1 or 4

) =

Probability (obtaining 1

) +

probability (obtaining 4)

= \frac{150}{800} + \frac{75}{800} = \frac{225}{800} = \frac{9}{32}

Q. A biased dice was rolled 800 times. The frequencies of the various outcomes are given in the table below.

When the dice is rolled, the probability of getting a number which is a perfect square is (approximately).

$\frac{9}{32}$

$\frac{11}{32}$

$\frac{13}{32}$

$\frac{15}{32}$

The possible perfect squares which can be obtained are 1 and 4 . Required probability = probability (obtain- ing 1 or 4 $) =$ Probability (obtaining 1 $) +$ probability (obtaining 4)
$= \frac{150}{800} + \frac{75}{800} = \frac{225}{800} = \frac{9}{32}$
