This is what's called an 'and' probability because we are looking for the probability that die 1 rolls an odd number and die 2 rolls an odd number.
1, 2, 3, 4, 5, 6
Out of those numbers on a die, 3 of them are odd. So the probability that die 1 rolls an odd number is 3/6 and the probability that die 2 rolls an odd number is also 3/6.
And means multiply (most of the time), so to find the probability that both dice show an odd number, we will multiply 3/6 x 3/6.
3/6 x 3/6 = 9/36 = 1/4
Hope this helps! :)
