Whilst shopping, the probability that Caroline buys fruit is 0.4. The probability that Caroline buys a CD is 0.6. Buying fruit and buying a CD are independent of each other. Work out the probability that she only buys fruit, only buys a CD, or buys both.

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.

i'm not sure on this one, most likely correct.
