3) In November, the rain in a certain valley tends to fall in storms on several days' duration. The unconditional probability of rain on any given day of the month is 0.700. But the probability of rain on a day that follows a rainy day is 0.800, and the probability of rain on a day following a nonrainy day is 0.400. Find the probability of rain on November 1 and 2, but not on November 3.
