Without looking Tammy takes a marble out of the bag that contains 10 red marbles 15 green Marbles and 25 blue marbles to record its color and return some marble into the back can you repeat this process many times how many times can drink expected to pull out a red marble
To determine the number of times Tammy can expect to pull out a red marble, we first need to calculate the total number of marbles in the bag. The bag contains 10 red marbles, 15 green marbles, and 25 blue marbles, for a total of 10 + 15 + 25 = 50 marbles.
Since Tammy is returning each marble back into the bag after checking its color, the probability of drawing a red marble remains constant for each draw. We can therefore calculate the expected number of times Tammy can pull out a red marble by multiplying the probability of drawing a red marble by the total number of draws.
The probability of pulling out a red marble can be found by dividing the number of red marbles (10) by the total number of marbles in the bag (50). So, the probability is 10/50 = 1/5.
Let's assume Tammy repeats the process "n" times. Therefore, the expected number of times she can pull out a red marble is given by:
Expected number of red marbles = Probability of drawing a red marble × Total number of draws
Expected number of red marbles = (1/5) × n
Since we don't have an exact value for "n", we cannot determine the exact number of times Tammy is expected to pull out a red marble. However, the expected number of red marbles will be proportional to the total number of draws.
Therefore, if Tammy were to repeat the process many times (large "n"), the expected number of times she can pull out a red marble will approach (1/5) × n.

10 reds out of 50 marbles, so 1/5 of the time you can expect a red.
