Nicole Hamilton creates clear and concise videos to support students in Pre-Algebra, Algebra I, Algebra II & Trig, Geometry and IB Mathematical Studies, arranged by topic in each subject area.
She is currently expanding the library of videos to include additional topics in Statistics, Calculus and more advanced areas of math.
If you need a support video and you are unable to find it in the existing library, please reach out!
I couldn’t understand even a thing, with my math exam in two days. All it took me was to watch this 14 minute video. Now I’m thorough with the concept. Thank you so much!❤
Hi... This is one of the trickiest (not hardest, but trickiest) topics of probability because of the tiny subtleties. There is a difference between asking about it raining and you walked (in which case, yes, you do multiply) or asking what the probability is that you walked if you know that it rained. If something is a certainty, then by default, then by definition, the probability is in fact 1. Hope that helps!
Many texts use the rows and columns interchangeably (as the interpretation and calculations are unaffected), but I believe it's more popular to put the gender (independent variable) in rows and the dependent variable in columns-- opposite to my example
isn't p/y supposed to be one? I thought it was payments per year. You only make one payment, which is the initial deposit, so isn't it supposed to be p/y=1 and c/y=4?
Hi.. P/Y and C/Y should be kept the same in questions that don't include the topic of repayments. P/Y is needed for loan repayment questions. The initial money put into the account isn't a payment, it's a deposit. Hope that helps!
What is the reason for the background music ? It is not assisting me to listen and learn the information that is presented about the correlation coefficient.
Thanks so much for this video! It really helped me understand why I dropped marks in my homework and tests and the way you explained it made so much more sense than my maths teacher!😂
Hi... If you're interested in a playlist on Probability, I've linked my Probability playlist below: ru-vid.com/group/PLVYFumktsk6RWQ7EQhfc4VzSztaM_ZUzo
You're welcome... I'll try to give you a short and simple answer here, but not sure if it's sufficient. :) If you have a conditional probability question, the denominator is the given condition, since we know that that thing has occurred (so it's essentially the new total)... And the numerator is the the event, specifically within the given condition.
