There are 6 adult chaperones, 21 female students, and 23 male students on a bus for a field trip. What is the probability that a randomly chosen person on the bus is an adult chaperone or a male student?

A. 2/3

B. 29/50

C. 1/2

D. 1/29

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.
