Probability - addition and multiplication rules

[maggydietcurrent]

your Video was very great. it saved me. thanks. you explain better than some university professors. keep up the good work.

never knew this would become such a clutch for my first exams thats happening tomorrow 😭 THANK YOU

[synriser]

What a great explanation, thanks again. Who said math is boring, just get your marbles out?

[DavidGiangNamPham]

Thank you sir, your explanation, rules and diagram really helps

[rockstar]

Reminds me of highschool! 😊😊😊 Thank you sir!

[shaistatabraiz]

Your videos are good and helpful keep up the good work!!!!

Great explanation sir, , explaining probability through tree shape much better than function shape only ( which official Gmat book used )

Wow just realised how many subs this channel has

I have been wondering for a long time. Are you using a mouse to write?

[jiadp]

Tecmath can you please solve this problem using the method you explained. You are walking to a ranger station. You go to one fork and you randomly go left. You go to another fork and randomly go right. There is one correct path. What is the probability you are on the correct path. Please make a video on this I am really confused. Thanks again and very good explanation. Please.

I love math and you. I hope I can connect with you

*Probability*
0:09 Flipping A Coin or Marbles in a bag
1:19 Flipping a Coin 2 times

Possible results of Flipping a Coin 2 times

Independent Events
5:25 Mutually Exclusive events

6:25 Takeing Out Marbles from A Bag
7:18 Dependent Event
*”Without Replacement”*
Means—> Not Replacing Marbles.
Not Replacing Marbles causes the Changing Probabilities

Possible Results For Pulling 2 Marbles from a bag of 3 Blue Marbles and 2 Red Marbles

11:03 Probability of 1 Red and 1 Blue

How about maths of moving from one point to another through two or more different substrates that let you go different speeds?

On the last part, why did you put 2 taken out randomly but only removed one apple? I thought two apples would be removed.

Off topic? I was out of work but trying really hard to find a job. I managed to get 9 interviews in 11 months. I didn't get any of the jobs. The job centre guy insisted that with that many interviews he "couldn't understand why I hadn't got a job." i.e using his logic I had a greater chance of getting a job the more interviews I had. I tried to tell him the independent events probability applied because each interview was an independent event. As he was a bureaucrat he did not like it one bit being answered back to. am I right in saying the two possible outcomes of each interview resulting in a job offer are Yes and No and that the outcome of say the 6th interview does not affect the 7th interview. Hence each outcome was 1 in 2? This of course ignores things such as with every failure I got more and more desperate and this desperation showed. It also ignores things like if there are say 6 people interviewed including me then the probability of any one of us getting the job was 1 in 6. If you've read this far then thanks. Great channel by the way.

[siddigagaffar]

when finding out the probability, do i simplify my answer in an exam?

[neelamrajawat]

can you plz make a video for compounded interest problems??

[GoodDeedsLeadTo]

Probability does not add up to 1 in case of independent events?

[Johnmckenna-wewj]

Sorry I meant it was just dividing statics it has really planned any thing to predict probability other than statistics

Bro sounds like Jeremy Clarkson from Top Gear
