Given: P(E1) = 1/6, P(E2) = 1/3, P(E3) = 1/6

To find: P(E4)

We know that the sum of probabilities of all elementary events of a random experiment is 1. Therefore,

P(E1) + P(E2) + P(E3) + P(E4) = 1

Substituting the given values, we get

1/6 + 1/3 + 1/6 + P(E4) = 1

Simplifying the above equation, we get

P(E4) = 1 - (1/6 + 1/3 + 1/6)
P(E4) = 1 - 2/3
P(E4) = 1/3

Therefore, the probability of E4 is 1/3.

Answer: c) 1/3
