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).A. `(9)/(32)`B. `(11)/(32)`C. `(13)/(32)`D. `(15)/(32)`

Answer» Correct Answer - A
The possible perfect squares which can be obtained are 1 and 4. Required probability =probability (obtaining 1 or 4) = Probability (obtaining 1) + probability (obtabninig 4)
`=(150)/(800)+(75)/(800)=(225)/(800)=(9)/(32)`.
