Answer:
4/5
Step-by-step explanation:
The bag contains 50 coins and each coin marked from51 to 100.
∴, total no. of outcomes =50
The prime numbers between 51-100 are : 53,59,61,67,73,79,83,87,91,97 i.e., total 10 numbers.
∴, no. of composite numbers between 51-100 =50-10=40
∴, probability that the number on the coin is not a prime number is
=40/50
= 4/5
