A fair die is tossed 60 times and the results are recorded in the table
| Number of die | 1 | 2 | 3 | 4 | 5 | 6 |
| Frequency | 15 | 10 | 14 | 2 | 8 | 11 |
Find the probability of obtaining a prime number.
\(\frac{7}{30}\)
\(\frac{1}{6}\)
\(\frac{7}{15}\)
\(\frac{8}{15}\)
Explanation
Prime number in the experiment are 2,3 and 5 with frequencies 10,14 and 8
P(obtaining a prime number) = \(\frac{10+14+8}{60}\)
= \(\frac{32}{60}\) or \(\frac{8}{15}\)
