    a. 0.857

    Step-by-step explanation:

    Data provided in the question

    Significant rainfall = 30%

    Significant rainfall in the prior day = 75%

    Significant rainfall the prior day in the case of no significant rainfall = 40% of the time

    Now the probability of no significant rainfall on a day is

    = P (B) + P (B : A) - P (A)

    = 0.75 + 0.40 - 0.30

    = 0.85

    Hence, the correct answer is a. 0.857
