Thanks so much for this, it just wasn't going in with my maths teacher today and my functional maths skills level 2 retake is tomorrow 😬 this has clicked!!

[@jeffellis9462]

Hope you passed ok
im 65 and this tutorial has clicked so i can understand my grandsons home work now

[@maisulhana4558]

Thx alot for this vid

[@graceanderson303]

why did you add on the first two questions but then times on the second question?

[@Moezm759]

A little late but it's because,
When the word And comes so, P(A And B), you multiply so P(A) × P(B)
When the word Or comes, you add so switch × with addition sign

[@musamaster9648]

for the bag b why do you have to doo the tree twice

[@aaronsebastian8349]

Because they give the questions liks that

[@jaiden4775]

Thank u sir Pugh

[@Sam-mz6ix]

Thanks

3:12 why only these two circles? why did you choose the other two instead?

[@ruth_ava]

Because that is not what the question asked mate

[@faizan7343]

@@ruth_ava lol

[@musamaster9648]

cuz its asking about the red counters not blue (3 years late u probs dont give a shi)

[@yeetdotexe1257]

on question 1 why did you add up 30/90 and 16/90 and not 20/90 and 24/90??

[@charliesheaf1328]

That’s all the question asked for

[@ruth_ava]

Because part B only asks for the probability of one counter of each colour taken not the same colour.

[@ttee1397]

why did you add 1/12 but it asks for one match can you please explain thank you

[@simonogren]

Because matha

[@ruth_ava]

Because there were two different probabilities for winning and losing so you add both different probabilities to get you the answer

[@ruth_ava]

1/4 x 1/3 = 1/12 and that was a lose or win so that’s how he had to add 1/12 to 6/12
