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).

Options

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

Answer

A

Explanation

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)`.
