Answer:
6/11
Explanation:
We are not told which number cube shows a 4; it can be the first one or the second one.
If the first number cube is a 4, this gives us the options of:
4 and 1; 4 and 2; 4 and 3; 4 and 4; 4 and 5; 4 and 6.
However if the second number cube is a 4, this gives us
1 and 4; 2 and 4; 3 and 4; 4 and 4; 5 and 4; 6 and 4.
We cannot count "4 and 4" twice; this leaves us with 11 total possibilities.
Out of these 11, only the sum of 4 and an odd number will be odd:
1 and 4; 3 and 4; 5 and 4; 4 and 1; 4 and 3; 4 and 5.
There are 6 ways to have an odd sum out of 11 total possibilities; this gives us a probability of 6/11.
