Answer:
C, The marble is 3 times as likely to be black as it is to be white.
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong.
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong.
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct.
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.

Answer:
A.3/7
Step-by-step explanation:
1/2 - 1/14
We need to get a common denominator of 14
1/2 * 7/7 = 7/14
7/14 - 1/14 = 6/14
We can simplify by dividing the top and bottom by 2
3/7
D)300% because it is an increase so you'd do 240/80=3•100=300
11 and 2/11 because 46 divided by 11 is 44 plus 2 is 46
