A bag contains 4 red marbles and 1 yellow marble. What is the probability of drawing a red marble, then replacing that marble, then drawing a red marble again on the second pick?

16/25

Step-by-step explanation:

We have 4 red marbles and a total of 4 + 1 = 5 marbles.

Probability is simply (# times a specific event can occur) / (# times any event can occur).

Here, the probability of drawing a red marble is: 4/5 (because there are 4 red marbles to choose from and a total of 5 marbles to choose from).

We replace the marble afterward, so the probability that the second pick is also red would still be 4/5.

Then, multiply the two fractions together: (4/5) * (4/5) = 16/25.

Hope this helps!

answer: x= -2y

step-by-step explanation:

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
