Question

In a lottery of 50 tickets numbered 1 to 50, one ticket is drawn. find probabiltiy that the ticket drawn bears a prime numbers

Answer 1

Prime number upto 50 = 2,3,5,7,11,13,17,19,23,29,31,37,41,43 and 47

Number of primes= 15
Total numbers= 50
P(prime) = 15/50 = 3/10 or 0.3

Answer 2

Answer:

The probability of getting prime number is 0.3.

Step-by-step explanation:

Total number of tickets is 50.

The prime number between 1 to 50 are 2,3,5,7,11,13,17,19,23,29,31,37,41,43 and 47. The count of prime number between 1 to 50 is 15.

Probability that the ticket drawn bears a prime numbers is

$P=\frac{\text{Count of prime number between 1 to 50}}{\text{Total number of tickets}}$

$P=\frac{15}{50}$

$P=\frac{3}{10}$

$P=0.3$

Therefore the probability of getting prime number is 0.3.
