Question

Find the probability of even numbers that can be possible only with 1,2,3,4 in 4 digits?

Answer 1

total number of events=4
total number of outcomes=2
probability is 2/4
=1/2

Answer 2

Answer:

Probability of  all possible even number of 4 digit is 1/2.

Step-by-step explanation:

Given: Digits are 1 , 2 , 3 , 4.

To find: Probability of  all possible even number of 4 digit.

All possible 4 Digit Numbers = $^4P_4=4!=24$

Possible 4 digit even numbers  = 3 × 2 × 1 × 2 = 12

$Probabilty=\frac{Number\:of\:Favorable\:outcome}{Total\:number\:of\:outcome}$

$Probability=\frac{12}{24}=\frac{1}{2}$

Therefore, Probability of all possible even number of 4 digit is 1/2.
