~ ANSWER=1/2 ~
Simple probability is found by counting all the results which fit requirements and dividing by all possible results.
To find probability of two results in a row, multiply chance of first result by chance of second result.
Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.
There are 5 white marbles
There are 4 red marbles
There are always 20 marbles in all
5/20*4/20=1/4*1/5=1/20 or 1/2
By coincidence, the same as the chance of drawing the white marble in one draw.
2Ɩ • 2w = Ain^2
Ɩ (length) and w (width) represent the number of tiles on each side
Because each tile is 2in, the number of tiles needs to be multiplied by 2
After multiplying the amount of tiles on each side by 2, you must multiply the products
Since the answer is area, you’ll need to write your answer as a square with the proper unit of measurement (inches)
Ain^2
