Ten students are applying for 3 positions on a team. the students include 4 boys (adam, alex, anthony, and arnold) and 6 girls (abbey, aurora, agnes, alice, amanda, and anna). all the students have an equal chance of being selected. find the probability that the students selected will include: a) at most 1 girl b) adam, anthony, and alice c) agnes and 2 other students

Best ResponseYou've already chosen the best response.0Well, you certainly don't 'have to'  if one really wanted to they could solve this by just drawing a (massive) tree diagram, but I think we can be slightly more clever about it,

Best ResponseYou've already chosen the best response.0Don't worry, you can just draw a treediagram with 720 branches and be sure of the answer.

Best ResponseYou've already chosen the best response.1[(6/10)(4/9)(3/8) + (4/10)(6/9)(3/8) + (4/10)(3/9)(6/8)] + (4/10)(3/9)(2/8)

Best ResponseYou've already chosen the best response.1wait the ordering doesn't matter so you have to divide the first part by 3? or 6?

Best ResponseYou've already chosen the best response.0I preferred it in the old form you posted: (6/10)(4/9)(3/8) x 3 + (4/10)(3/9)(2/8)

Best ResponseYou've already chosen the best response.0You don't. But your answer there accounts for it by multiplying by three.

Best ResponseYou've already chosen the best response.0OK. If there are three boys chosen, the chance is (clearly... I hope) (4/10)(3/9)(2/8) The only other option is 1 girl and 2 boys. This can either be GBB, BGB, BBG, but the chance of each is still (6x4x3)/(10x8x9). So your answer \[\frac{(6 \times 4 \times 3) \times 3 + 4 \times 3 \times 2}{720} \] is right.

Best ResponseYou've already chosen the best response.0Yes; there's still a total number of 10*9*8 = 720 in the denominator; the order of the multiplication above is irrelevant. @ azntiger627  FACEPALM  if you honestly have no idea which part this is then you have clearly done nothing on this work, and do not deserve help until at least attempt it.

Best ResponseYou've already chosen the best response.1Newton already solved part (a) for you above. but i think you should go over permutations and combinations before trying to solve the question above. good luck!

Best ResponseYou've already chosen the best response.0There names all begin with A, which is annoying, so just called them ABC. There are 6 ways of arranging them: ABC ACB etc. And 10 x 9 x 8 possible ways in total. Continue from there.
