Each day, John's mother gives him money before he goes to school: 50% of the time he gets $5, 35% of the time hegets $10 and the rest of the time he gets $20.Determine the expectation and variance for how much money John gets each day.For the next 100 school days, John plans to save all the money his mother gives him. What is the approximateprobability he is able to save more than $1000? Assume independence.If he realizes he has to spend an average of $4 a day with a standard deviation of $0.75, what is the approximateprobability that he saves less than $400? Assume independence.

Let X denotes the amount of money (in $) John gets each day. Given that 50% of the time he gets $5,…
