Answer

Explanation:

Step1: Identify total number of trials

The total number of times Rodrigo picks an item is 18.

Step2: Identify number of favorable outcomes

The number of times a washer is picked is 4.

Step3: Calculate probability

The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So, $P=\frac{4}{18}=\frac{2}{9}$.

Answer:

$\frac{2}{9}$
