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
Since a cube has 6 sides, you have a 4 in 6 chance of getting a number less than 5 each time you roll the dice. You would take how many times you want to roll it (360), divide it by the number of sides (6), and multiply it by 4 since you know you have a 4 in 6 chance. So it should be 240. This is strictly mathematical though and you should not consider it accurate since there are many variables when rolling it.
The number 100 is ten times less than 1000.
20 less than 2 times a number is 40 = 2x - 20 = 40Let x = the number2 times a number = 2x20 less than = - 20is 40: =40Translating it into mathematical symbols :2x - 20 = 40

Thirty decreased by three times a number is six less than three times the number. Find the number.

Any number less than 3.
six less than fourteen times a number
13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
There are six sides on the die, and two of them are less than three. So when you throw the die, there are two possibilities out of six total possibilities that the die will land on either one or two - this means it should happen about 2/6ths, or 1/3rd of the time. Since you're throwing the die 54 times, all that's left to figure out is what 1/3rd of 54 is: 54*(1/3) = 18 So, it should land on a number less than three about 18 times.
15 less than 7 times a number is:15-7n
two less than three times a number is 28
Three times a number is 10 less five times the number can be put in the form of an equation that looks like this: 3x = 5x-10. Now just solve for x...
numbe is 5
You should replace or compensate for the loss. You would expect no less.
It is 100 times less than it.
