What else can I help you with?
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
If I roll a dice 100 times how many times should I expect to see the number three?
When rolling a fair six-sided die, the probability of rolling a three on any single roll is 1/6. If you roll the die 100 times, you can expect to see the number three about ( \frac{1}{6} \times 100 ), which is approximately 16.67 times. Therefore, you should expect to see the number three about 17 times in 100 rolls.
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 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.
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
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".
What percent of the time will you get a 1 if you roll a die 60 times?
16.66... % of the time - if the die is fair. And the percentage is not affected by the number of times you roll it.
