An analyst has a limit order outstanding on a stock. He argues that the probability that the order will execute before the close of trading is 0.20. Thus, the odds for the order executing before the close of trading are .a. one in four b. one in fivec. four to one d. five to ond

b. One in Five

Step-by-step explanation:

To calculate probability, we need to know the formula:

in this case the probability is given in its decimal form, which is = 0.20

∴ to be able to use our formula easily, we will need to convert the probability to its fraction form.

which is 0.20 = ( to do this, just simply put a 1 under the decimal point and replace the remaining values of 20 with zeroes)

reducing to its simplest form gives .

Hence, relating it to our formula, we can see that the number of possible out comes is = 1

and the total number of outcomes = 5.

This means that the probability that the order will execute before the same of closing is the same as  1 in 5

90

Step-by-step explanation: 25% of 120 is 30

120 - 30 = 90
