Step 1
Obtain the proportion of adults whose favourite season is spring:
The value of probability is obtained by:
$P\left(E\right)=\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$
$P\left(\text{Adults whose favorite season is spring}\right)=\frac{\text{Number of adults whose favorite season is spring}}{\text{Total number of outcomes}}$
$=\frac{250}{2500}$
Step 2
Therefore, the correct answer is “Option B.) $\frac{250}{2500}$.
