Best ResponseYou've already chosen the best response.1_,_,_ 60 countries are competing for 3 places, right ? so first place can be taken by any one of the 60 countries in 60 ways after this, second place can by taken by remaining 59 countries in 59 ways. lastly, for the third place can by taken by any of 58 in 58 ways. so total outcomes are : 60 x 59 x 58 can you try applying similar logic for b) ?
