A school took 225 children on a trip to a theme park.
After the trip the children had to write about their favourite ride at the park from a choice of three.
The table shows the number of children who wrote about each ride.
| \multirow{2}{*}{} | Ride written about | |
| | The Drop | The Beanstalk | The Giant | Total |
| \multirow{3}{*}{Year group} | Year 7 | 24 | 45 | 23 | 92 |
| Year 8 | 36 | 17 | 22 | 75 |
| Year 9 | 20 | 13 | 25 | 58 |
| Total | 80 | 75 | 70 | 225 |
Three children were randomly selected from those who went on the trip.
Calculate the probability that one wrote about 'The Drop', one wrote about ‘The Beanstalk’ and one wrote about The Giant’.
