To find the percentage of calls that occur on sunny days, we calculate the weighted average of sick calls based on the weather. For sunny days (20% of days), 1.8% of employees call in sick. For not sunny days (80% of days), 1.4% of employees call in sick. The calculation is as follows: (0.20 * 1.8) / [(0.20 * 1.8) + (0.80 * 1.4)] = 0.36 / (0.36 + 1.12) = 0.36 / 1.48 ≈ 0.2432 or 24.3%.
