If i roll a die 90 times how many times can i expect to roll a 6?
pr(six) = 1/6 → expected 6s in 90 rolls = 1/6 × 90 = 15
How many times would you expect to roll an even number on a 6-sided number cube labeled 1-6 if you rolled 40 times?
The expected value is 20 times.
What is the probability of rolling a number greater than three if you roll a die two times?
fifty percent
If you roll a die 30 times how many times should you expect to roll a number less than 3?
The expected number of rolls under 3 is the number of rolls times the probability of rolling less than 3. So: E(rolls less than 3 out of 30) = 30 * 1/3 = 30/3 = 10
If you roll a dice 100 times how many times would you roll a three?
100/6 = 16.6 times
If i roll a die 90 times how many times can i expect to roll a 6?
pr(six) = 1/6 → expected 6s in 90 rolls = 1/6 × 90 = 15
How may time can you expected to roll a 4out of 18 rolls on a six sided sides?
Three times.
How many times would you expect to roll an even number on a 6-sided number cube labeled 1-6 if you rolled 40 times?
The expected value is 20 times.
If you roll a dice 160 times about how many times would you expect to get 7?
The expected number of times is the probability x number of throws. Since you have a prob of 1/6 for a seven, then (1/6) * 160 = 26.67 times you would have success. We generally would round up the expected number of successes to the whole number 27.

If you roll a die 30 times how many times should you expect to roll a number less than 3?
The expected number of rolls under 3 is the number of rolls times the probability of rolling less than 3. So: E(rolls less than 3 out of 30) = 30 * 1/3 = 30/3 = 10
If you roll a dice 100 times how many times would you roll a three?
100/6 = 16.6 times
Why Based on the experimental probability predict the number of times that you will roll a 5 if you roll the number cube 300 times.?
The expectation is 50 times.
If a dice is rolled 90 times what is the sum of the first and second roll expected to be on average?
If a DIE (not dice) is rolled 90 times, the expected value of the sum of the first and second rolls is 7 if you assume that the die is fair. It does not matter how many times you roll the die, as long as it is at least 2.
If you roll a fair number cube 30 times how many times would you expect to roll a odd number?
Type your answer here... 15
If you roll a fair number cube1 time about how many times can you expect to roll a 3 and then a 5?
Never. If you roll it 1 time, there can be no "then".
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.
