How do you estimate 3/4 - 1/8?  How much of 3/4 is left?
Marat540 [252]
They need a common denominator. so the common denominator is 8. so multiply the 3 and the 4 each by 2. so then you get 6/8. then subtract 1/8 from 6/8. so it looks like 6/8-1/8 and you'll get an answer of 5/8.

ValentinkaMS [17]

Answer:

11.84% approx.

Step-by-step explanation:

Expected return = Respective return × Respective probabilities

                           = (18.5 × 0.71) + (-7.6 × 0.29)

                           = 10.931%

Probability          Return          Probability ×(Return - expected return)²

0.71                         18.5               0.71×(18.5 - 10.931)² = 40.67573

0.29                        -7.6               0.29×(-7.6 - 10.931)² = 99.585409

                                                             Total                = 140.261139%

SD=[\frac{\text{total probability(return-expected return)}^2}{\text{total probability}}]^{(\frac{1}{2})}

= [\frac{140.261139^2}{140.261139}]^{\frac{1}{2} }

= 11.84319 ≈ 11.84% approx.
