    What I've learned from this lecture is that I need to go play more craps to study for the GRE. Probability involving 6's all day. great lecture.

    at 50:30, the possible outcomes of two dice rolls whose sum is 8 are {(2,6), (3,5), (4,4), (4,4), (5,3), (6,2)}. so the probability is 6/36 = 1/2.

      you need to count 4,4 only once because it is the same in either ways

    Really enjoyed the way the lessons were taught. It's impeccable !!
    .
    I have one slightest doubt: in the last qs (56:00), how come the probability P(of getting 1 greater than 4) = 2/6? I didn't entirely get this explanation. Could you kindly elaborate a bit more?
    Thanks in advance!

      Hey!
      Thanks for your feedback and question!
      For one roll, the probability of getting a number greater than 4 is the probability of rolling a 5 or a 6. As such, there are 2 possible success cases, out of the 6 total possible numbers, meaning P = 2/6. Does that make sense?

    I'm still debating on whether 1 is a prime or not. Lol (Edit: FYI, my math courses were pretty old school, 1990s).

      One is not a prime number as a number to be prime it needs 2 factors

    • @H.G.Wells-ishWells-ish
      @H.G.Wells-ishWells-ish Рік тому +1

      @bravo I think you mean 2 distinct factors. I get that. I was just musing a bit because one of my professors 30+ yrs ago was so indignant about 1 not being considered a prime anymore. He was in his 80s. Lol. It just depends on how it's defined today as opposed to in previous decades. My comment was more of a joke than anything.

    Hello Sir, I don't understand solving of Question 6. If remove 2 chips in bag, remains 10 chips in bag. Why second probability is 1/11? Maybe I can't understand due to English isn't my native language.

    • @manhattanprepgre7390
      @manhattanprepgre7390  Рік тому +1

      Hi! Good question! The important thing to keep in mind is that he pulls out the chips one at a time. So for the first chip, the probability is 1/12. Now there's only one fewer chip in the bag, so the probability for the second chip is 1/11. Does that make sense?

      Hi! Thanks for your question. Our GRE Free Prep Hour series is not intended to be a complete program. Each teacher decides what they would like to teach, so some topics might be covered more than once and some might not be covered at all. It's possible that some students might find Free Prep hour to be enough to get to their goal score, but if you are aiming for an especially high score, then use this series as a supplement to your main course, books, or studies.

    I had doubt in question 10
    How is probability for 4+,4+ 2/6 and not 2/36
    Please explain this I'm stuck here

      @manhattanprepgre7390  Рік тому +1

      Hi, Pushpak! Thanks for your question. Sorry, I kind of rushed through that calculation in the lecture. The probability of a single roll greater than 4 is 2/6 (two possible numbers (5 and 6) out of 6 total possibilities). To get two rolls greater than 4, we multiply 2/6 x 2/6, which is 4/36, or 1/9. Does that make sense?
