The last seems most appropriate
The probability that Sarah takes one piece of each fruit is; (10x - x²)/100
<h3>
Probability</h3>
We are given;
- Number of fruits in the bowl = 10
Thus, remaining fruits are;
- Number of apples = 10 - x
Probability that at least one will be banana = x/10
Probability that at least one will be apple = (10 - x)/10
Thus;
Probability that she takes one piece of each fruit is;
x/10 × (10 - x)/10
⇒ x(10 - x)/100
⇒ (10x - x²)/100
