You can put this solution on YOUR website!
p(snow or sleet) = .3 last Sat (chance of snow or sleet last Saturday was three out of ten)
p(snow or sleet) = .4 this Sat (chance of snow or sleet this Saturday was four out of ten)
......
P(Independent Events) = the product of the individual probabilities.
P(snow or sleet Last AND this Sat) = .3%2A.4 = .12
