A bag contains tiles of different colors. Roshan randomly selects a tile from the bag and returns the tile to the bag after recording the color. He picks a green tile 6 times, a red tile 20 times, a blue tile 7 times, a purple tile 8 times, and a black tile 4 times. Based on the results, what is the theoretical probability that the next tile Roshan picks will be green?

Answer:

6/41

Step-by-step explanation:

6 + 7 + 20 + 8 = 41 so that is number of tiles he took. 6 of those were 41 so therefore, the chance is 6/41

Answer:

There are four red marbles and six blue marbles in all, for a total of ten marbles.

Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.

The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.
