Recall that the probability of obtaining k Heads in n independent coin tosses is (nk)pk(1−p)n−k , where p is the probability of Heads for any given coin toss. Find the value of ∑k=0n(nk)pk(1−p)n−k . (Your answer should be a number.)

What are the options

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.
