Answer:
3/8
Step-by-step explanation:
Probability = Favorable Outcomes / Total Outcomes
There are 3 even numbers and e odd numbers.
P(Even Number) = 3/6 = 1/2
P(Odd Number) = 3/6 = 1/2
Probability it lands twice on an even number and once on an odd number = 1/2 * 1/2 * 1/2 = 1/8
What we must remember here is that the question does not say that the first 2 rolls are even and the 3rd roll is odd.
We must find the number of ways of getting Even, Odd Combinations which are 3!/2! = 3 (EEO, EOE, OEE)
The Required probability = 3 * 1/8 = 3/8
