# Expected Value (Q2d)

Time for the tabular approach to finding the expected value of x. In other words, I use a table to keep track of my calculations.

Remember to make use of the order of operations:

1. (B)rackets … (no operations within brackets here)
2. (E)xponents … (no exponents here)
3. (D)ivision … (no division here)
4. (M)ultiplication … Multiply each x by its corresponding P(x)
5. (A)ddition … Add up each xP(x) in the column to get ∑xP(x)
6. (S)ubtraction … (no subtraction here)

NOTE: The order of division and multiplication can be switched, as well as addition and subtraction

ALSO NOTE: This order is sometimes expressed as P.E.M.D.A.S.

1. (P)arentheses
2. (E)xponents
3. (M)ultiplication
4. (D)ivision
5. (A)ddition
6. (S)ubtraction
