To find the probability of drawing a red ball, we use the formula for probability:

$P(\text{Red}) = \frac{\text{Number of red balls}}{\text{Total number of balls}}$

Given:

• Red balls = 2
• Blue balls = 3
• Black balls = 5

Total number of balls:

$2 + 3 + 5 = 10$

So, the probability of drawing a red ball is:

$P(\text{Red}) = \frac{2}{10} = \frac{1}{5}$

Therefore, the probability of drawing a red ball is $\frac{1}{5}$.
