probabltity=desired outcomes/total possible

the ones that sum to 4 are (depends on what die)
1 and 3
3 and 1
2 and 2
2 and 2
4 combinations


how many different possibitlies
6 sides so 6*6 for 2 dice

so 4/36 is porbablity or 1/9


1/9 of all of them so

about 1000/9 times or about 111.1111 times, (rounded to 111 times)

Answer: about 83

Step-by-step explanation:  the answer is 83 since

3/36 = 1/12 = 0.083 is the probability of rolling a 4

0.083*1000 = 83 is the number of times we expect to roll a 4 out of 1000 trials
