Three coins are placed in a bag. each coin is labeled “1”, “2”, or “3”. a coin is drawn from the bag, recorded, and then placed back in the bag. estimate the probability that the coin labeled “1” will be drawn next.

3 3 2 2 1 1 3 3 2 2

a. 3/4
b. 1/4
c. 4/5
d. 1/5

1/5

Step-by-step explanation:

Probability = required outcome / all possible outcome

From the question above, A coin labelled '1', '2', or '3' is drawn from a bag , and it is being REPLACED back in the bag after it has been recorded, we are now asked to estimate the probability that  the coin labeled '1' will be drawn next.

Our required outcome is the number of '1' which is 2 and all possible outcome is the total numbers of '1', '2' and '3' which is 10

since the ball are replaced after each drawn then;

Probability = required outcome / all possible outcome

                  =2/10

                   =1/5

Therefore the probability that the coin labeled '1' will be drawn next is 1/5

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
