fuk i ahte probablitlyfilo_romz said:what did everryone get for that question? question 8 c) .. i know it was either 2017 or 2018.
and oh yeah .. that probability question with the tickets.
this is how i did it :
there's three tickets each 100
so probability of red tickets winning all three is:
100/300 * 99/299 * 98/298 coz its without replacement
so dats: 1617/44551 .. =/
den the next one was if each ticket wins
so its
100/300 * 100/299 * 100/298
which equals to: 10000/267306 .. hmm
i prefer calculus
