Given:
quarters and dimes ; 19 pcs
total value of quarters and dimes is 4
q + d = 19
0.25q + 0.10d = 4
q = 19 - d
0.25(19 - d) + 0.10d = 4
4.75 - 0.25d + 0.10d = 4
-0.15d = 4 - 4.75
-0.15d = -0.75
d = -0.75/ -0.15
d = 5
q = 19 - d
q = 19 - 5
q = 14
There are 5 pieces of dimes and 14 pieces of quarters.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Red = 4
Blue = 6
Yellow = 2
Total = 4 + 6 + 2 = 12
Probability is that event divided by total event, so
Probability of Blue = 6/12 = 1/2
Since, we put the blue again back into the bag, so we still have same amount of each (this is with replacement, probability).
So, 2nd time:
Probability of Blue = 1/2 (same)
Now, we need to multiply these to get probability of blue IN A ROW:
1/2 * 1/2 = 1/4
