Given:
Tickets are marked numbers from $1$ to $50$. And, one ticket is drawn at random.
to find: Probability of getting a prime number on the drawn ticket
Total number of tickets are $50$.
Tickets which are numbered as prime number are $2,3,5,7,11,13,17,19,23,29,31,37,41,43,47$
Total number of tickets marked as prime is $15$.
As We know that the Probability = Number of favorable outcomes/ Total number of outcomes
Hence, the probability of getting a prime number on the ticket $=15/50=3/10$
