Find the probability of obtaining a prime number.
\(\frac{7}{30}\)
\(\frac{1}{6}\)
\(\frac{7}{15}\)
\(\frac{8}{15}\)
Correct answer is D
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 \(\frac{8}{15}\)
