Answer:
The correct option is (B).
Step-by-step explanation:
The conditional probability of an event, say <em>A</em> is the probability of that events (A) when it is known that another event, say <em>X</em> has already occurred.
For example, consider the experiment of drawing two marbles from jar consisting of 8 white and 2 red, without replacement. The probability of selecting a red marble after a white marble is known as conditional probability.
In this case it is provided that:
- 40% of the students are licensed drivers
- 55% students are female.
The statement:
"the probability that a student who is a licensed driver is a male"
Is a statement of conditional probability.
This is because it is known from previous information that the student is a licensed driver and we need to determine the probability of this student being a male.
Thus, the correct option is (B).
