1:30:22 i think it should be 6 not 5 because its has to be more than 6 flights

As a student, it is much better when you go in blind so don't apologize to do it because A- Seeing you, a teacher, take time and think, makes me feel like it is okay not to get things first try, and that is very helpful. B - I get to understand how you think, and how I should tackle every problem. Thank you for your help, you have been a lifesaver.

thank you so much for all of the IB work you're uploading to youtube. I truly believe you're the reason I have any chances of passing my finals this May. You explain everything so well. You're a true saviour.

1:11:12 you did binomial pdf for exactly 6 flights but the question says more than 6. Answer is 0.169

[nadiahamada]

[andresyengle]

I had my paper 2 today and this video literally saved my butt on like 1/2 the questions

[djrkm]

as a physics HL student for 6b) I will without hesitating say that k represents the DECAY CONSTANT of a element and its formula is ln/half life

[smk]

for exercise 4 C, you could have done it a more easy way. u know theres 100 students from which 48% are girls, meaning that theres 48 girls. it says 25% of those do theatre so multiply .48 x .25 and u get .12 which is the answer :)

Thank tou so much bro I love you so much

[rose_natasha]

Your answer for 8e is wrong bcs it is binomial cdf and should be 1- so = .169...

[kevinelzouki]

58:30 yo bro its a paper 2 so if we use gdc plug y1=x and y2= the equation using t as 1 gdc will give u an intercept which is 10.5 which is acceptable according to the answer sheet. That works right? Cz it past 10 times

[racoesp]

at time 24:00 it was simply 25% of 48% which is basically 12% right?

[lakshaynarain]

I think this is a silly question but do I have to mention in the exams where I used GDC for calculation.

[kevinelzouki]

0:38 YOUR i thought u were 19 or 20 bro u look so younggg lmao i was like "this kid is almost the same age and destroys math and look at me"
