The probability of a rain-free weekend is 0.6962
The probability = Number of favorable outcomes / Total number of outcomes
The probability of rain on Saturday = 62/100
= 31/50
The probability of rain on Sunday = 49 /100
The probability of rain on Saturday and Sunday = The probability of rain on Saturday × The probability of rain on Sunday
= (31/50) × (49/100)
= 0.3038
The probability of rain free weekend = 1 - The probability of rain on Saturday and Sunday
Substitute the values in the equation
The probability of rain free weekend = 1 - 0.3038
= 0.6962
Hence, the probability of a rain-free weekend is 0.6962
