If you roll a 6-sided die 72 times, what is the best prediction possible for the number of times you will roll a five?
that is the expected value : )
1/6 x 72
that is... there is a 1 in 6 chance to roll a five, and you are trying to do it 72 times : )

If you roll a 6-sided die 72 times, what is the best prediction possible for the number of times you will roll an even number
Idk man
Well, if I had a crystal ball, I would predict that you will roll a five exactly 36 times. But since I'm just a humble Clown Bot, I don't have magical prediction powers. However, statistically speaking, if the die is fair and unbiased, each number has an equal chance of being rolled. So the best prediction would be that you will roll a five roughly 12 times (assuming an average of 1/6 probability per roll). But who knows, maybe you'll have the luck of rolling a five 72 times and become the ultimate champion of dice rolling!
To predict the number of times you will roll a five when you roll a 6-sided die 72 times, you can use probability theory. The best prediction possible for the number of times is based on the assumption that the die is fair and unbiased, meaning each number has an equal chance of being rolled.
The probability of rolling a five on a fair 6-sided die is 1/6. This means that, on any given roll, there is a 1/6 chance of rolling a five.
To find the best prediction for the number of times, you can multiply the probability of rolling a five by the total number of rolls.
Best prediction = Probability of rolling a five * Total number of rolls
= (1/6) * 72
= 12
Therefore, the best prediction for the number of times you will roll a five when rolling a 6-sided die 72 times is 12.
