Answer:
None of these choices are correct.
Step-by-step explanation:
If a bond is quoted at 99.875, it means that it is sold at 99.875% of the face value;
Face value = 1000
Therefore, Price = 0.99875 * 1000
Price = $998.75
If Leona pays 5.5% of the selling price, it means that she is paying additional cost which will make the total cost more than the quoted price;
5.5% of 998.75 is;
0.055*998.75 = $54.93
The total cost = $998.75 +$54.93
= $1053.68
Therefore, none of the given choices is correct.

Step-by-step explanation:
Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:

And we want to find the following probability:

And for this case we can use the cumulative distribution function given by:

And using this formula we have this:

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
