Find 4/5 of 500.
4/5*500=400
You will roll 400 sixes.
Given a biased dice with a probability of 4/5 to show a 6, one would expect to roll a six around 400 times in 500 rolls. This calculation is based on the concept of expected value in probability theory. However, the actual outcome can vary due to randomness.
The student's question deals with the concept of expected value in probability theory. The expected value is calculated by multiplying each possible outcome by their respective probability and then adding these values.
In this scenario, with the dice having a probability of 4/5 to show a 6 on every roll, the expected value of 500 rolls would be: 4/5 * 500 = 400.
That means, if you roll the dice 500 times, you would expect to roll a six around 400 times.

Answer:
The integers are 2,3,4
Step-by-step explanation:
Let one integer be =
Since, the integers are consecutive, so they will increase by one.
So, 2nd integer will be =
3rd integer will be =
It is given that the 3 integers add up to 9.
So, we have the sum equation as:
Solving for
Combining like terms.
Subtracting both sides by 3.
Dividing both sides by 3.
∴ 1st integer =
2nd integer =
3rd integer =
