In a bin containing 500 marbles, 160 are red, 220 are blue, and 120 are green. in a bowl of 25 marbles scooped from this bin, how many would be expected to be blue?
a. 6
b. 8
c. 11
d. 22

I need help on this too... but i think it is about 11ish can someone help me

11,
220/500 = 0.44
0.44x25=11

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.
