A biased dice was rolled 600 times. The frequencies of the various outcomes are given in the following table :
| Outcome | 1 | 2 | 3 | 4 | 5 | 6 |
| Frequency | 160 | 130 | 120 | 50 | 60 | 80 |
Now the dice is rolled once, the probability of getting a number which is a perfect square is :
1
\(\frac{1}{12}\)
2
\(\frac{13}{30}\)
3
\(\frac{4}{15}\)
4
\(\frac{7}{20}\)
