(B) The total number of outcomes is $50$ (since boards are numbered $1$ to $50$).Prime numbers between $1$ and $50$ are: $2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47$.Counting these,we find there are $15$ prime numbers.The probability $P$ of selecting a prime number is given by the ratio of favorable outcomes to total outcomes:$P = \frac{15}{50} = \frac{3}{10}$.

There are boards numbered $1$ to $50$ in a box. One board is selected at random. Find the probability that the number on the board is a prime number.
