Answer

Explanation:

Step1: Calculate total pieces picked

$8 + 7+4 + 5=24$

Step2: Calculate probability of picking straight

The number of straight - pieces is 8. Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$, so the probability is $\frac{8}{24}=\frac{1}{3}$

Answer:

$\frac{1}{3}$
