In how many ways can six states be selected from the top 11 states with the most murders if the order of the six states does not matter? round your answer to the nearest whole number.

When the order of selection does not matter, the applicable concept is combination otherwise permutation would have been applicable.

Number of states = 11
States to be selected = 6

Therefore,
Number of ways of selecting 6 states from 11 states = 11C6 =  11!/(11-6)!6!= (11*10*9*8*7*6)/(1*2*3*4*5*6) = 462
