Abasket contains 11 pieces of fruit: 4 apples, 5 oranges, and 2 bananas. jonas takes a piece of fruit at random from the basket, and then beth takes a piece at random. what is the probability that jonas will get an orange and beth will get an apple?

The probability of Jonas getting an orange is 5/11, and as he has an orange there are only 10 pieces of fruit left in the basket. 
Now, the probability of Beth getting an apple 2/10 or 2/5.
So to get the final result we need to multiply Jona's with Beth's:  

(5/11)·(2/5) = 10/55
