P (Rain) = \(\frac{1}{4}\)
P (No-Rain) = \(\frac{3}{4}\)
Required probability = P (Rain on Tuesday) x P (No-Rain on Wednesday) = \((\frac{1}{4})(\frac{3}{4}) = \frac{3}{16}\)

Probability of raining on Tuesday = 0.25 = \(\frac{1}{4}\)
Probability of NOT raining on Wednesday = 1-0.25 = 0.75 = \(\frac{3}{4}\)
The probability that it will rain on Tuesday of the next week, but NOT on Wednesday = \(\frac{1}{4}\)*\(\frac{3}{4}\) = \(\frac{3}{16}\)
Probability of NOT raining on Wednesday = 1-0.25 = 0.75 = \(\frac{3}{4}\)
The probability that it will rain on Tuesday of the next week, but NOT on Wednesday = \(\frac{1}{4}\)*\(\frac{3}{4}\) = \(\frac{3}{16}\)
