You toss two dice 1000 times How many times do you expect to have the sum of the two dice equal to 7?

There are two dice with 6 side each. The probability of any single unique outcome is 1/6 * 1/6 = 1/36
Now the question becomes how many ways can you roll a 7 using two dice. It might be easiest to just show this as a table:
1 6
2 5
3 4
4 3
5 2
6 1
So there are 6 ways to roll a 7 using two dice. That means the probability of rolling a 7 is 6/36 = 1/6.
Finally, to answer the question, we will multiply the probability of success (getting 7) with the number of attempts (how many times you rolled the dice). This equals 1/6 * 1000 = 166.66... or in real-life terms: 167 (remember that in real life no-one has 2.5 children)

If a 6 sided dice is rolled 12 times how many times would you expect to roll a number less than 4?
6
If a 6 sided dice is rolled 12 times how many times would you expect to roll a prime number?
36 times. But also, you might get the opposite result 36 times.
If the dice is rolled 450 times how many times would you expect to get 4?
The probability of rolling a four on a single roll of a fair die is 1/6. So the expected number of 4s in 450 rolls is 450*1/6 = 75.
How many times would you roll a sum of seven on one number dice?
never.. the highest number on a dice is a 6
What is the probability of rolling a number greater than or equal to 8 with two dice given that at least one of the dice must show a 6?
5/36
If you roll a dice 60 times about how many times would you expect it to get a 1?
60
How Many Times Would Pip Expect To Roll A Number Greater Than 2 A Fair Dice 150 Times?
He should expect it 100 times.
If a 6 sided dice is rolled 12 times how many times would you expect to roll a number less than 4?
6
If a 6 sided dice is rolled 12 times how many times would you expect to roll a 6?
36 times. But also, you might get the opposite result 36 times.
If you roll a dice 300 times about how many times would you expect it to land on 5?
1/6 of all outcomes should be a 5. 300*1/6=50 This is the answer regardless of what you are rolling for. You would find whatever number you want and average about 50 times if you were to roll the dice 300 times. You might not get exactly 50, but it won't be far from that. There are faces on a die, and the odds of any one of those 6 numbers showing up is 1 out of 6 times. The above is only true if the dice are not rigged in any way ("loaded dice"). Now, if only one number likes to keep coming up, you might be dealing with loaded dice. In that case, the dice are made for cheating and the mathematical laws of average no longer apply.

36 times. But also, you might get the opposite result 36 times.
What is the probability that the sum of the two dice is greater than or equal to 20?
