Imagine a given capital market where a risk-free asset with a return, rf, of 6% per period is traded. On the given capital market, the only assets traded, besides the risk-free, are stocks in firm A, firm B and firm C. Thus, no other risky assets are traded on the capital market. The price today (t = 0) of a stock in A is DKK 50. On the capital market, all participants agree that in one period (to time t = 1) there are only 4 possible states for the value of stock A, cf. table 2.1 below:

State	Probability	Price at t= 1 in firm A
1	0,15	47,00
2	0,15	44,50
3	0,30	43,50
4	0,40	45,00

No matter which state is realized, a dividend of DKK 10 per stock in firm A is paid in the next period (after t = 0 and before t = 1). The realized return of stock B in the next period, for the states, is given in table 2.2 below:

State	Realized return of stock B in next period
1	-0,0700
2	0,1300
3	0,1500
4	0,0800

Calculate the expected return and the variance of the return in the next period, for firm A and B.
