1/8 + 2/4= 1/8 + 4/8 = 5/8 =0.625
The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.
The sum of 4/5 and 1/2 is 1 3/10
A sum of 4 is more likely. Out of the 36 possible outcomes with a pair of 6-sided dice, only one will have a sum of 2 {1-1}. Three of the possibilities sum to 4. {1-3, 2-2, 3-1}
1/14 + 5/14 + 2/14 = (1+5+2)/14 = 8/14 = 4/7
13/12
23/48
13 over 12
The sum of 5/7 and 2/4 is 1 3/14
1/8 + 2/4= 1/8 + 4/8 = 5/8 =0.625
1/6 + 2/3 + 1/4 = 2/12 + 8/12 + 3/12 = 13/12 = 1 1/12
The probability of rolling a sum of 5 with two die is 4 over 36, or 2 over 18, or 1 over 9.
plus indicates that it is a sum (not a difference): 1/4 + 2/4 = 3/4. You can just add the numerators, since the denominators are the same.
12 over 11
1/6+2/3+1/4 = 2/12+8/12+3/12 = 13/12 = 1+1/12. One and one twelfth
The sum of 2/6 and 4/5 = 1 2/15
The sum of 4/5 and 1/2 is 1 3/10
