    I have a question/dilemma about a math problem for you math experts: There's a sports lottery game where there's 14 football matches (each match can end in 3 ways, the local team wins=1, there's a draw=X, or the visiting team wins=2). Let's say for instance I have to guess 10 of those matches (1, X or 2). What are the chances of randomly guessing any of those 10 matches out of 14? I looked on various sites and they used the formula ''3 to the power of 10'' resulting in 1 in 59049 chance but it's incorrect and it's a ridiculously large number too, they calculated the chances assuming there's 10 matches in total and not 14. How can I calculate step by step the correct chances of guessing 10 out of 14 matches?

  • @grygerroo8963
    @grygerroo8963 7 років тому +1

    i know some guy who asked this.. why are the chances of winning the lottery in the millions. when really if you only had to choose 1 number from a set of 49 numbers your chances of getting that number right are 1 in 49, so after that seeing that numbers don't show up twice your chances of getting that second number is 1 in 48, then 1 in 47 for the 3rd then 1 in 46 for the fourth. so technically the chances of winning the lottery should be one in 49+48+47+46+45+44 which is 279...

    I feel bad to point it out( Coz your videos help me score high) but the last part of the explanation is wrong. The winning numbers 3,15,47,49 are not arranged in that order. Since you said that the order in which the numbers on the lottery appeared didnt matter. Hence shouldn't the probability be 24 divided by 60C4 since those 4 winning numbers can be arranged in 4X3X2X1 ways??

    • @datarachit
