Atrain has 10 cars numbered 1 through 10. if the cars are coupled randomly, what is the probability that the first 3 cars are in car number order?

1/720

2/15

1/5,040

Hence, the probability that the first 3 cars are in car number order is:

A train has 10 cars numbered 1 through 10.

If the cars are coupled randomly, what is the probability that the first 3 cars are in car number order.

The probability of the three cars is independent and we know that when the events A,B and C are independent then

As, the first car chosen is to be selected among 10 cars.

Hence, the probability is:

similarly the second car is to be selected among 9 cars.

Hence,

similarly,

Hence, the probability that the first 3 cars are in car number order is:
