How many times should you expect to roll a 5 on a number cube if you roll the cube 4,000 times?
what is 1/6 of 4000 ?
666.666 repeating but do I write 666? cause it can't happen 666.666 of the time.
I would round off to the nearest whole number, or 667
Ok thank you
The six faces of a fair cube are numbered 1 to 6. If the cube is rolled 300 times,what is the expected number of a 3 will land face up
To determine how many times you should expect to roll a 5 on a number cube if you roll it 4,000 times, we need to consider the probability of rolling a 5 on a single roll.
A standard number cube has six sides numbered 1 to 6, so the probability of rolling a 5 on a single roll is 1 out of 6, or 1/6.
To find the expected number of times a 5 will appear, you can use the expected value formula:
Expected Value = Number of Trials × Probability
In this case, the number of trials is 4,000 and the probability is 1/6.
Expected Value = 4,000 × 1/6 = 666.67
Therefore, you can expect to roll a 5 around 666 times when you roll the cube 4,000 times.
