  • This cleared up my questions about the counting principle. Do you have any videos about Pascal's Triangle? My mathbook doesn't explain that very well.

  • no pascal's triangle yet!

  • I need help with this question. If possible use an equation and if you could explain that would be great :)

    A letter is selected at random from the alphabet. Find the probability that the letter is a vowel or comes from the word HELPFUL

  • Really helped me out. Thanks!

  • Today I learned the mathematical proof on why I shouldn't haphazardly guess on the SATs. Thanks for the math and motivation...

  • thanks! this was very helpful :)

  • @petmaster495

    If we have 2 pair of blue shirrt,1 white shirt,pair of blue pant and pair of white pant,in how many ways one can wear itI got answer as 8 but its actually 6...how is that

  • Left handed people are smarter. Anyway, I'm confused, my professor told us we can't used 0 in 1st dial...I was wondering why did you apply 0 in 3:14...as far as I know we haven't yet discussed permutation. And I'm not sure if the 0 thing I'm asking you is combination?.

  • For the multiple choice question, aren't there technically 6 ways to answer each question because you can either pick A-E or decide to not answer at all? Or in the problem are we assuming that you have to pick a choice?

  • As to the final problem, if > 7/10 is failing and there are 10 questions and 5 possible answers for each, what method can you use to determine in what number of the possible 9,765,625 outcomes you would score < 7/10?

    Great video!

  • thank uu soo much!!

  • thanking u sir
