(TCO 2) Given the data below, calculate the expected return, variance, and standard deviation of the following company. In a recessionary economy, which is expected to occur with a 30% probability, the expected returns would be -5%. In an expanding economy with an expected probability of occurrence of 20%, the expected return would be 10%. In a normal economy, expected to occur 50% of the time, the expected return would be 5%.

I am trying to figure out the probability, expected value, variance, and standard deviation for a series of dice rolls. For example, if I roll a six-sided die in an attempt to roll a 1, and it takes me 7 rolls before a 1 appears, what are those answers? I have figured out the probability equation: P(P-1)^x where x is the number of rolls - 1 so for 7 rolls the probability would be: 1/6(1-1/6)^6 = 0.05581632... Further where I...
