If you mean 2 x 2 then yes, because they have alike variables. But if you mean 2•2 then no, because they don’t have alike variables.

since ΔCDW similar to ΔUVW, then

UW/CW = UV/CD

UW = CW•UV/CD

CU+CW = CW•UV/CD

CU = CW•UV/CD - CW

= 26•132/24 - 26

= 143 - 26

A bag contains five white marbles and five black marbles. What is the probability of drawing a white marble, not replacing it, a

Lelu [443]

~ 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.
