Re: What is the probability of rolling two fair dice and having

We need to find What is the probability of rolling two fair dice and having each die show an odd number?
As we are rolling two dice => Number of cases = \(6^2\) = 36
Let's solve the problem using two methods:
Method 1:
Now there are 4 outcomes possible (Odd, Odd), (Odd, Even), (Even Odd), (Even, Even) and there is an equal chance of each of them happening
=> P(Both will be odd) = \(\frac{1}{4}\)
Method 2:
Both the die can be odd in 3*3 (=9 ways), as in the first roll we can get any number out of 1, 3, and 5. And in the second case also we have these 3 choices.
