1. Find a degree 3 polynomial that passes through the points (-2,3),
(-1,1), (1,-1), and (3,1).
I can find the equation to a parobla, but when I get the answer to this one its different then the one on the answer key. I'm using the equation y=ax^2+bx+c is this the right equation?
2. You flip 2 fair coins (H or T on each), roll a single die (1-6), then draw a card and take note of its
suit (spades, clubs, diamonds, or hearts). How many elements are in the sample space? Give 3
examples of an element you could find in the sample space.
I got 62 but the answer key is says 96.

a degree 3 polynomial is,
p(x) = ax³ + bx² + cx + d
plug in the four points and you will get four equations and four unknowns, a, b, c, & d
2)
2 * 2 * 6 * 4 = 96
2 choices for coin 1 × 2 choices for coin 2 × 6 sides to a die × 4 card suites
ex 1) H T 6 Spades
ex 2) H H 1 Hearts
ex 3) T H 6 Diamonds
3)
Probability of all 3's is, (1/3)^40 ==> very small
