Leaving Cert Probability: Independent Events

preview_player
Показать описание
In this video I take a look at Independent Events from the probability section of leaving cert higher level maths. Independent event are where the outcome of one event in no way affects the outcome of another event.
The formulas for independent events are:
P(A)=P(A|B)
P(B)=P(B|A)
P(AnB)=P(A).P(B)

I'm not very good at maths so I am probably wrong Sir, but I tried.

i) they are independent. *maybeee...* i got 0.84 both times, so i hope its right
ii) i dont know, i think theyre not independent... i feel like i made a mistake, but i will retry.
