red balls=3
blue balls=4
total balls=3+4=7
probability of selecting 3 red balls=3/7 ×2/6×1/5=1/35

so now P=2/6
and so on .

i promise this is the answer i go to k12 and got the answer correct
0.89, 1.009, 1.017, 1.02, 1.1 is the correct order
X - $5 bills
y - $10 bills
x + y = 12
y = 5x

y = 10
10 $10 bills and 2 $5 bills
