Don't know how I ended up back here after like 5 years. But, I remember going from 10/75 in a mock exam to 100% across all past papers and 100% in my actual exam after watching all this guys videos for literally just 1 week. Graci.
I’m going to do hypothesis testing with 2.5% significance level, H0: p=0.05, testing for H1: p>0.05. To see if this is significant, to see i can reject my null hypothesis to see if the probability of going from 10 to 100% across all exams is more than 5%. Props to @TLMaths for teaching me this.

genuinely I've stopped enjoying maths at school, but these videos make me feel confident in it again. thank you so much 👍
how's it going now?
I was looking for pple like u
My maths teachers took a whole week to teach us this concept. You taught me in 4 mins. Thank you really helpful!
💯
A really clear and helpful explanation, many thanks.
Great vid!😍
My teacher didnt even explain these terms, had to come here to do my homework
Just brilliant!
thanks for the help
thank you!
Why is it that when working out venn diagrams you cannot use P(A) x p(B) to find P(AnB) but when in normal probability this rule applies?
The rule applies if and only if A and B are independent. If they are not independent then P(AnB) does not equal P(A)xP(B)
@@TLMaths Ok i understand, Thanks
Are you suppose to mention that P(A or B)=P(A) + P(B) for mutually exclusive events?
That is a consequence of being mutually exclusive and you can use that to show that A and B are mutually exclusive.

What would a Venn diagram with independent events look like? Thanks.
The Venn diagram of independent events could look much the same as one of dependent events.
