A security with normally distributed returns has an annual expected return of 18% and standard deviation of 23%. The probability of getting a return between -28% and 64% in any one year is .

$95.45%

Explanation:

The computation of the probability of getting a return between -28% and 64% in any one year is shown below:-

Particulars                                                      Percentage

Total probability                                              100%

Less:

Probability that return will be lower

than -28%                                                        2.28%

1- (NORMDIST (-28%,18%,23%,TRUE)

Probability that return will be More

than 64%                                                        2.28%

(NORMDIST (64%,18%,23%,TRUE)

Probability of getting a return between

-28% and 64%                                               $95.45%

answer; /// that is so (false);

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
