Answer:
.753
Step-by-step explanation:
Let Ps = probability both marbles are the same color.
Let Pd = probability both marbles are a different color.
Pd = 1 -Ps
Let Pb = probability both marbles are blue
Let Pr = probability both marbles are red.
Let Pg = probability both marbles are green
Pb= 2/9 * 1/9 = 2/81
Pr= 4/9 * 3/9 = 12/81
Pg=.3/9 * 2/9= 6/81
Ps = Pb + Pr +Pg= 20/81
Pd =1-Ps= 61/81 = .753
Is this correct?
Answer: total cost earn=$1360
adult sold =45
student sold =80
adult cost twice as student cost so we can say adult sold 45+45=90
so total sold=90+80=170
to get the cost of 1 meal we divide 1360 by 170
1360/170=8
one student meal cost=8$
one adult meal cost=8*2=16
total students meal cost=8*80=640$
total adult meal cost=16*45=720
640+720=1360
