Answer:
Step-by-step explanation:
Total marble = 8+5+4 = 19
n(Y) = 8, n(B) = 4 and n(R) = 5
Prob(R) = 5/17
Prob(B) = 4/16 {one marble is pulled out already}
Prob(R and B) = 5/17 × 4/16
= 5/17 × 1/4
= 5/68
EDIT:
Order of operations doesn't matter in addition. So you can add them in any order.
16/24 = 2/3
The answer is C, 33%, because it's equivalent to 2/3.
B. triangle and triangular prism
<span>In here, we will use the slope formula
in order to prove that ABCD is a parallelogram. The slope of AB must be equal
to CD and the slope of BC must be equal to DA. Using the formula m = (y1-y2) /
(x1-x2), we obtain the slope for AB = 0/4, BC = 1, CD = 0/4, DA = 1. We can say that ABCD is a parallelogram as it satisfies AB = CD, and BC = DA</span>
