Questions 1 - 7
Check out this video to learn about quadratics and how to find their intercepts, vertices, and lines of symmetry: https://www.youtube.com/watch?v=JpUanT9y4mw
​
Questions 7 - 10
Events A and B are independent if
P(A and B) = P(A) ∙ P(B)
or;
P(A|B) = P(A and B) ÷ P(B) = P(A)
​
Substitute in the values you're given and into conditions for independence. If the conditions aren't met, then A and B must be dependent events.
