What is the probability of getting a 2 or a 5 when a die is rolled?
2/6
3/5
1/3
3/6
Explanation:
Taking the individual probabilities of each number, getting a 2 is 1/6 and so is getting a 5.
Applying the formula of compound probability,
Probability of getting a 2 or a 5,
P(2 or 5) = P(2) + P(5) – P(2 and 5)
==> 1/6 + 1/6 – 0
==> 2/6 = 1/3.
