The probability that a number selected at random from the first 50 natural numbers is a composite number is -
A. $$\frac{{21}}{{25}}$$
B. $$\frac{{17}}{{25}}$$
C. $$\frac{{4}}{{25}}$$
D. $$\frac{{8}}{{25}}$$
Answer: Option B
Solution(By Examveda Team)
The number of exhaustive events = $${{}^{50}{C_1}}$$ = 50We have 15 primes from 1 to 50
Number of favourable cases are 34
Required probability = $$\frac{{34}}{{50}}$$ = $$\frac{{17}}{{25}}$$
