Gr 12 Probability # 5

In this video, we learn about Gr 12 Probability.

Did you know that I have a website full of maths and physical science courses!

The courses have:
1. More videos than on my Youtube channel - way more!
2. The courses are well organised which makes it easier to navigate.
3. You can ask me questions directly and receive answers faster than on Youtube.

Hello sir thank you for the videos, i have a question. At 2:18, when we write the grouped probability as 6! x 2!, where 6 are the units and 2 is the different parts of the unit of Jenna and todd, is the other units just 1! ? Hence why we don't include them in calculations - (1!=1)

Heyy kevin. For the unit aspect you stated that we group people that want to sit next to each other, into 1 unit and the rest will follow suit. But at 1:40 you said that there is 6 units. How is this so? Should'nt it be 2 units . Then the numerator should be 2! x 2! x 5! = 480 ?

Not me watching this the morning of trial paper 1

Or you could just use the grade 11 formula p(A and B)= n(A and B)÷n(s) that would be P(A and B)=2÷7
