Question

A dice is thrown, find the probability of getting a number which is exactly divisible by 2.
1. 2/3
2. 1/2
3. 1/3
4. 1/4

Answer 1

Correct Answer - Option 2 : 1/2

Formula used:

P(A) = n(E)/n(S)

where, n(E) → Required events, n(S) → Sample space

Calculation:

Let S be the sample space 

S = 1, 2, 3, 4, 5, 6

n(S) = 6

Let E be the event of getting exact divisible by 2 

E = 2, 4, 6

n(E) = 3

P(A) = n(E)/n(S)

⇒ P(A) = 3/6

⇒ 1/2

∴ The probability of getting exact divisible by 2 is 1/2
