Correct Answer – Option 4 : 1/6

Formula used:

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

Where, n(S) → sample space, n(E) → favourable event

Calculation:

Let S be the sample space

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

N(S) = 6

Let E be the event of getting 5

⇒ n(E) = 1

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

⇒ 1/6

∴ Probability of a getting 5 up is 1/6
