The probability a guest at a downtown hotel arrived via taxi is 0.42. the probability a guest arriving at a downtown hotel requested parking for a car is 0.29. assume a guest arriving by taxi is mutually exclusive of a guest requesting parking for a car. what is the probability of a guest arriving by taxi and requesting parking for a car?

0% probability of a guest arriving by taxi and requesting parking for a car.

Step-by-step explanation:

Two events are said to be mutually exclusive if one event precludes the other. That means that if A and B are mutually exclusive, the probability of A and B happening at the same time is 0%.

In this problem, we have that a guest arriving via taxi and requesting parking at the hotel are mutually exclusive.

So there is a 0% probability of a guest arriving by taxi and requesting parking for a car.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
