1) Ms. Roth has 2 black skirts and 3 gray skirts. She chooses a skirt at random on Monday, wears it, puts it back in the closet, and then chooses a skirt at random again on Tuesday. What is the probability that she
chooses a gray skirt two days in a row?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
