Question

Two digit numbers are formed from the digits 0,1,2,3,4, where the digits are not

repeated. Find the probability that the number so formed is a prime numbers.​

Answer 1

Answer:

hey mate here is your answer thank you

Step-by-step explanation:

→ Two-digit numbers are formed from the digits 0,1,2,3,4 without repeating the digits.

→ ∴ Sample space S={10,12,13,14,20,21,23,24,31,32,34,40,41,42,43}

→ ∴n(S)=16

→ (1) Let A be the event of getting an even number.

→ A={10,12,14,20,24,30,32,34,40,42}

→ ∴n(A)=10

→ probability, p( A) = n(A)/ n ( s) = 10/16 = 5/8

→  (2) Let B the event of getting a prime number.

→ B={13,23,31,41,43}

→ ∴ n ( B)  = 5

→ Probability, P(B)= n( B) / n ( s) = 5/16
