1/4
But what is the probability you will enter using an odd numbered door and sit in a green seat? Give your answer as a fraction.

Answer 1

The probability you will enter using an odd numbered door is 3/5, since there are three odd-numbered doors out of a total of five doors.

The probability you will sit in a green seat is 1/4, since there is one green seat out of a total of four seats.

To find the probability of both events occurring, you can multiply the two probabilities:

3/5 x 1/4 = 3/20

So the probability you will enter using an odd numbered door and sit in a green seat is 3/20.
