Best ResponseYou've already chosen the best response.02 other students? well there are 9 students left, and you choose 2

Best ResponseYou've already chosen the best response.0so 1 + 9 choose 2 , thats the favorable , and the denominator is again , the same

Best ResponseYou've already chosen the best response.0Oh by the way, if the answer to the first one is 1/40, and there are 10 * 9 * 8 ways of choosing the first 3 people, that implies that 18 teams will have those three in any order (they don't)

Best ResponseYou've already chosen the best response.01 for agnes, since they told you , you must choose her

Best ResponseYou've already chosen the best response.0It makes more sense just to say there are 10C3 ways of picking the 3 students (nCr takes into account the ordering problem) and one of these will be the 3 we want  so it is simply 1/10C3, not 3/10C3

Best ResponseYou've already chosen the best response.0sorry it is ( 1 * 9 choose 2 ) / 10 choose 3

anonymous

Best ResponseYou've already chosen the best response.0since there is 1 way to choose agnes, then there is 2 you have to choose among the 9 left

anonymous

Best ResponseYou've already chosen the best response.0I don't get how u set up the numbers in order to find the probability

Best ResponseYou've already chosen the best response.0well we use multiplication rule

anonymous

Best ResponseYou've already chosen the best response.0there are how many ways to choose agnes, one way. and for each of that way we can choose from whats left (9 people) 2 people we can choose. so we multiply these .

Best ResponseYou've already chosen the best response.0if you can do step one in k ways, and for each of those ways you can do step m, then there are a total of k * m ways
