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.

How do you show work for multi-step there are 18 students in Jacob's homeroom six students bring their lunch to school the rest
densk [106]

Answer:

The fraction that eats in the cafeteria is 2/3

Step-by-step explanation:

To find this, start by taking the number of students and subtracting the amount that bring their lunch.

18 - 6 = 12 that eat in the cafeteria.

Now that we have that number, divide by the total number of students.

12/18

To simplify this fraction, divide both numbers by 6.

2/3

Answer:

E. 31

Step-by-step explanation:

Add the values together.

4 (2/6) + 3 (3/6) + 2 (3/6) = 9 (8/6) or 10 (1/3)

multiply 10 by 3 to find how many thirds there are and add 1 to that number for the extra 1/3.
