Find the probability that a number picked at random from the set(43, 44, 45, …,…

Find the probability that a number picked at random from the set(43, 44, 45, …, 60) is a prime number.
  • A.
    (frac{2}{3})
  • B.
    (frac{1}{3})
  • C.
    (frac{2}{9})
  • D.
    (frac{7}{9})
Correct Answer: Option C
Explanation

Prime numbers = (43,47,53,59)
N = (43, 44, 45,…, 60)
The universal set contains 18 numbers.
The prime numbers between 43 and 60 are 4
Probability of picking a prime number = (frac{4}{18})
= (frac{2}{9})
