Mohit is selling candy bars. He has chocolate bars, nut bars, and mint bars. If a customer buys two bars, and the bars are not of the same type, how many different combinations are possible?
Yes there are 6 combinations but if you check some of them are same like -CB and MB , MB and CBSo there will be only three combinations
if you check you will get 3 combinations, because the question says that the two bars taken are not of the same type.
