Показать описание
If “Probability and P&C” questions on the #GMAT scare you, then you’re not alone. GMAT aspirants often profusely fear these questions, making it even more challenging (than it already is!) for them to get that Q90.
In this webinar, Shweta Koshija, e-GMAT’s Quant Product Creator, will start right from foundational concepts and slowly build structured approaches, using examples, which will enable you to tackle even the hardest questions on Advanced Topics on the #GMATQuant.

The session will be divided into 3 gradually progressing parts:
Part 1: Warm Up and Concept Recap: Theory Discussion and Feedback on how to solve questions effectively.
Part 2: Solve medium difficulty level questions using e-GMAT’s process skills.
Part 3: Solve hard difficulty questions to build upon the learning in Parts 1 and 2 of the session.

So, in just about 2 hours, Shweta will take you from basics to mastery! If you’re ready to cross that barrier you’ve been facing, join us on Feb 28, 10:30am ET / 9pm IST

As a bonus, you will get free access to 80+ questions on these Advanced Topics on e-GMAT’s Scholaranium platform (with 400+ Questions overall!), 25+ Video Lessons, 7+ Webinars, to help you in your GMAT Preparation.

I’m sure you don’t want to miss this! We’ll see you in the webinar.

Happy Learning!

In the last question Ma'am, can I assume a number straightaway? For example, 100 shirts in total. Thank you for the session!

My thought process for Sprint 1 - Q2:

The question says what's the probability that AFTER attempting 2 quizzes, he fails to get into D3. Since it's explicity mentioned that 2 quizzes were attempted, I take it for granted that D1 has been cleared and that event has already occured and therefore ONLY the probability of him failing D2 is to be evaluated, which is (1-0.7^10)

Can somebody please help me understand how my thought process is incorrect here? @egmat @gmatclub

Sprint 1 Q2. Why did we subtract b intersection C, there is nothing common in the probability of them completing their books right
