2. Find the probability of rolling a 4 on a fair die given that it will land even? VODA

Answer 1

Answer #1

For a roll of a fair die, there can be 6 possible outcomes which are {1,2,3,4,5,6}

Out of these outcomes, the outcomes that are even numbers are {2,4,6} i.e 3 outcomes

The probability of rolling a 4 on a fair die given that it will land even = 1/3
