The probability of picking a green marble the first time is 3/20 and the probability of picking a yellow marble the second time is 8/20.
probabilities are heavily related to percents so it would make sense that the probability of picking a color would be the number of that color divided by the total number.
note that it is really important that the problem said that the marble was replaced. If the marble was not replaced, the probability of picking a yellow marble the second time would be 8/19 if the first marble picked was not a yellow one.
I hope this helps.

Answer:
You can do this by rolling dice 4 times
Step-by-step explanation:
If you roll a fair dice 4 times and record the findings and their orders, you can generate 6^4= 1296 possible outcomes. You can pick 1-1000 as numbers and then re-roll all the dice if the number generate 1001-1296
To translate the dice result into a number you have to multiply the dice result as following:
1st roll multiplied by 6^0 = 1
2nd roll multiplied by 6^1 = 6
3rd roll multiplied by 6^2= 36
4th roll multiplied by 6^3= 216
Let's say you roll 1, 2, 3, 4
The number generated will be: 1*1 + 2 *6 + 3 *36 + 4 *216 = 985
Answer:
GCHE
Step-by-step explanation:
550 * 1.03 = 566.5 (Year 1)
566.5 * 1.03 = 583.495 (Year 2)
583.495*1.03 = 600.99985 (Year 3)
You can safely assume this is your answer: $601.00
