The probability for choosing green and red is 
<u>Solution:</u>
Given that , A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble.
We have to find what is the probability of choosing a green marble, not replacing it, and then choosing a red marble?
Now, we know that,

So, total possible outcomes = 1 red + 1 yellow + 1 blue + 1 green = 4

And now, total outcomes will be only 3 as we are not replacing the picked marble.

Hence, the probability for choosing green and red is 
Answer:
b
Step-by-step explanation:
Answer:
1st- 4, 2nd- 9, 3rd- 14, 4th- 19, 5th- 24, 6th- 29, 7th- 34, 8th- 39, 9th- 44, 10th- 49, 11th- 54, 12th-59
Step-by-step explanation:
1st- 4
2nd- 4+15-10= 9
3rd- 9+15-10=14
4th- 14+15-10=19
5th- 19+15-10=24
6th- 24+15-10=29
7th- 29+15-10=34
8th- 34+15-10=39
9th- 39+15-10=44
10th- 44+15-10=49
11th- 49+15-10=54
12th-54+15-10=59
Answer: 6x+5y=28
Step-by-step explanation:
Looking at the first equation, we can tell that x stands for notebooks and y stand for pens. Since this talks about the total cost with the amount of products they bought, we can automatically eliminate the subtracting answer choices.
Now, we know that 6x+57=28 is the correct answer because Sonja bought 6 notebooks and 5 pens. This becomes 6x+5y.
