GCSE Revision Video 32 - Probability trees

[selinanessa]

I hate drawing probability trees, I can only imagine the frustration of drawing them on the computer. Thank you for all your efforts :)

Hegarty Maths never fails to enlighten my mind. Unrivaled teaching

There is an error at 26:36. The probability of getting a number 2 on the second go, is not 2/6, but 3/6 as the number 2 has not been drawn yet. This makes the answer slightly different: 16/42

I have my GCSEs beginning in 19 days and this has helped so much in comparison to my crappy Year10 teacher. Thanks a lot, you're a life saver!

[GodsTreasure]

Your videos have really been helping me. I'm not even doing GCSE math. I'm doing IGCSE but they have still been a great help. Thanks a lot

[ActuallyAudacity]

I never knew this was so easy :) Thanks loads...Helped a tonne

[soultreatment]

This video was extremely useful for me and helped me a lot with my GCSE Mathematics revision. Thank you very much, Mr.Hegarty. I subscribed and liked this video to show my appreciation.

[jakebarratt]

Thanks for the video! I'm a little bit confused ( question 25) on how you got 11/10 I thought it would be 10 biscuits if she took two out of the tin out of 12? It's probably me missing something but could anyone explain would be much appreciated!

+HEGARTYMATHS You made a mistake in the november 12 NC Question. I t supposed to be 3/6 for 2 in the first subsequent tree diagram check it out maybe im wrong who knows?

[chandrapalungwa]

I had never though probability will be easy. when I learned in school I literally don't understand what they are saying and I leave all the question blank but when I saw your video It helps me a lots and I feel much more better than before. thanks for this video. really appreciate..

[soultreatment]

22:53 Is that fraction not supposed to be 2/9 ? Because she takes 2 sandwiches out. Thanks a lot for making these videos by the way, they have helped so much

[jamesobi]

The correct answer is 16/42....slight error caused by incorrectly specifying P(2) as 2/6 instead of 3/6 (try it...). Great videos.

[farid]

thank you so much
it was really helpful for me. However, the Q21 is answered wrong
the answer will be16/42
not 14/42

[beccafoster]

why didnt you put the 'Y' in a yellow colour!

[premisvision]

For Q25 are you sure it is right? it says 'Carolyn takes at random two biscuits from the tin' in your workings you only took 1 away from 20 and only took 1 away from the amount of biscuits for each type. Surely it would be 10/18 for the plain biscuits and 3/18 for the chocolate biscuit and 1/18 for the ginger biscuit?
