Question

The fruit basket at a summer camp contained 4 oranges and 5 apples. Carlos chose

Answer 1

So the probablity is desired outcomes divided by total possible outcomes

so assume duncan gets an orange on the first try, that would be 4/9

then carlos picks another fruit, also assuming that duncan got an orange so 5/8

then these are dependant on each other so we  multiply
4/9 times 5/8=20/72=10/36=5/18
