There are a total of $5 \times 10 = 50$ blocks in total.
The probability of selecting a triangle is $\frac{10}{50} = \frac{1}{5} = 0.2$ or $20\%$.
Malaya has $5$ different shapes of blocks: rectangle, rhombus, square, trapezoid, and triangle. She has $10$ of each shape. She selects a block at random.
What is the probability she will select a triangle?
