Answer:
Explanation:
Given
Probability of a person to not enter into a bar or ducking is
Probability of a person to enter into a bar
(Probability of a person to not enter into a bar or ducking)
Substituting the given value, we get
Probability of a person to enter into a bar
Total three men attempts to enter into the bar and their course of action is independent of each others
Thus, probability of observing the first two walking into the bar and the third ducking will be equal to the product of individual probabilities

Answer:
Suppose the cost per hour incurred in operating a cruise ship is 3a + b dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.)
<em>The speed at which the ship would maximize cost is </em>
Explanation:
The problem can be solved using differentiation to get the minimum value of the speed to travel between the two ports. Step by step calculation is contained in the attached images;
