Answer:
The of getting an even number in first and an odd number second is
.
Step-by-step explanation:
Given,
Total number of outcomes = 36
We have to find the probability of rolling an even number first and an odd number second.
Solution,
Firstly we will find out the possible outcomes;

So the total number of outcomes = 9
Now according to the formula of probability, which is;

Now on putting the values, we get;
P(of getting an even number in first and an odd number second)=
Hence The of getting an even number in first and an odd number second is
.
