Karen has a bag containing the following marbles: 3 red marbles
4 green marbles
1 yellow marble
Karen randomly selected a marble from the bag and
then put it back in the bag. She did this a total of
200 times, and 67 times the marble she selected
was red. What was the difference between the
number of times she actually selected a red marble
and the number of times she should have expected
to select a red marble? For this question you’ll have to explain the answer

answer: a clock

step-by-step explanation:

two data sets with the same median will not have the same varaibility

step-by-step explanation:

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
