According to the profession's estimation, the share price had 60% probability to increase by 64% and 40% probability to decrease by 46% after 5 years. (i) Find the maximum profit and loss made the share (ii) Find the expected percentage change in the share. ********************************************************** Law of integral indices (2?5^n)^2 + 25^n OVER 5^n 更新: Another Question : Solve sin (30°-y) = cos50° for 0 ° < y < 301° 更新 2: Law of integral indices (2?5^n)^2 + 25^n OVER 5^n 你都未simply晒.....

最佳解答:

(a)(i) maximum profit =1000000*(1+64%)-1000000=640000 maximum loss =1000000*(1-46%)-1000000=-460000 (ii) expected percentage change in the share =0.6*0.64+0.4*(-0.46) =0.2 =20% (2?5^n)^2 + 25^n / 5^n = (2?5^n)^2 + 5^2n / 5^n =(2?5^n)^2 + 5^n =4(5^2n)+5^n Solve sin (30°-y) = cos50° for 0 ° < y < 301° sin(90-x)=cosx So 30-y=40 or 180-40=140 or -220 y=-10 or -110 or 250 So y=250
