To find the probability of drawing a ball with a specific characteristic, we need to calculate the ratio of the number of balls satisfying that characteristic to the total number of balls in the box.
Box contains balls numbered: 11, 12, 13, 14, 15, 16, 17, 18
11, 13, 17
Total number of balls in the box = 8
Number of balls with prime numbers = 3
Probability of drawing a ball with a prime number = Number of balls with prime numbers / Total number of balls
= 3 / 8
= 3/8
12, 14, 15, 16, 18
Number of balls with composite numbers = 5
Probability of drawing a ball with a composite number = Number of balls with composite numbers / Total number of balls
= 5 / 8
= 5/8
Therefore, the probability of drawing a ball with (a) a prime number is 3/8, and (b) a composite number is 5/8.

Answer:
To find the probability of drawing a ball with a specific characteristic, we need to calculate the ratio of the number of balls satisfying that characteristic to the total number of balls in the box.
Given:
Box contains balls numbered: 11, 12, 13, 14, 15, 16, 17, 18
(a) To find the probability of drawing a ball with a prime number:
Prime numbers among the given balls are:
11, 13, 17
Total number of balls in the box = 8
Number of balls with prime numbers = 3
Probability of drawing a ball with a prime number = Number of balls with prime numbers / Total number of balls
= 3 / 8
= 3/8
(b) To find the probability of drawing a ball with a composite number:
Composite numbers among the given balls are:
12, 14, 15, 16, 18
Total number of balls in the box = 8
Number of balls with composite numbers = 5
Probability of drawing a ball with a composite number = Number of balls with composite numbers / Total number of balls
= 5 / 8
= 5/8
Therefore, the probability of drawing a ball with (a) a prime number is 3/8, and (b) a composite number is 5/8.
