  • Perhaps did u make a mistake on the video because it say total #of people is 21

    13 speak english

    9 speak chinese with that right there is a total of 22 people already

    plus the 2 that do not speak either english nor chinese

    that makes a total of 24 people in total so thats what lost me with this probability video

  • @EzaTraviezza13 There are 3 people who can speak both English and Chinese. You count 3 people twice; therefore you need to subtract 3 from 24. Thanks.

  • @ihsankayili Thanks for watching.  Yes, I do. I will try to upload more videos.

  • thank you Turkish teacher greetings from Turkey :)

  • @SERKMEN Thank you.

  • ok wouldnt the total be 24 13+9+2=24

  • @mynewlife27 13 + 9 - 3 = 19

    Sorry, I didn’t understand your questions?
