The best thing about you is that you can simplify quant questions easier than anyone. I had no idea about combination watching so many stuffs. But this time, it seems like I've learned something. I can't wait to be a part of your course.

You are awesome!! Making a scary subject easier to get going. Thanks!

[@Spybuoy]

Just a small note, representing 8! in 8C2 as (8 * 7 * 6!) helps in calculating the number of combinations in a more effective manner. Would like a video which integrates combinations into probability.

[@adityabhat5189]

Thank you so much so making this video Phil! That last example was particularly helpful. You are doing a fantastic job! I'm looking forward to more of these type of quality videos. Best Regards.

Does this include picking two men or two women in different orders? For example is picking Dan and then Earl going to be the only thing considered or is picking Earl and then Dan also considered? In my opinion, no matter what order you pick them in, you get the same two so...

[@md.saddamhossain2034]

@The Tested Tutor the concept you presented is superbly simple, as always. But, maybe, we don't need this lengthy formula and calculation. There is another simple way to avoid this lengthy formula: Suppose, 8C2 = (8*7)/2! ; again 10C3= (10*9*8)/3! ( there is an obvious pattern, i am not explaining it ). For ncr , the numerator multiples are starting from the number(n) and multiplied by next numbers (r times). For 10C3; n=10, r=3; so in numerator there should be three numbers starting from 10 and another two numbers are 9,8 ; in denominator 3!. Another example to illustrate, 11C4 = (11*10*9*8)/4!

[@TheTestedTutor]

A tip for advanced users for sure, thank you

[@pratikthorat3480]

Is Manhattan 5lb enough to prepare for GRE quants for a perfect quants score or shall I do more. I mean since the time I have started watching your videos, quants have been quite easy (solvable rather) but apart from 5lb and mocks which other resources would you recommend ?
