Suppose you have a bag of marbles. You know that there are 10 marbles in the bag, but you do not know what colors they are. You select a marble 40 times, each time
recording its color before putting it back. In 8 out of 40 trials you select a purple
marble.
Based on the data, how many purple marbles do you estimate are in the bag? Explain
your prediction

8 out of 40 trials- 8/40

simplify that and it becomes 1/5

1/5 of 10 is 2

so, I'd estimate there are 2 purple marbles.

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
