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
