And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
And the variance is defined as:
Step-by-step explanation:

So then the probability of no win would be given by the complement:
We can define the random variable X who represent the amount of money that we can win.
And we can use the definition of expected value given by:
And we know that each time that we win we recieve $1 and each time we loss we need to pay $1, so then the expected value would be given by:
We can calculate the second monet like this:
And the variance is defined as:
