The chance that both come up red is 2/3.
<u>Step-by-step explanation</u>:
First regular die :
The total outcomes are {1,2,3,4,5,6} = 6
Painted red are odd numbers {1,3,5} = 3
Second regular die :
The total outcomes are {1,2,3,4,5,6} = 6
Painted red are one less than perfect square which is 4-1 is {3} = 1
- Probability (both red) = (red in 1st die / total outcome) + (red in 2nd die / total outcome)
P(both red) = 3/6 + 1/6
⇒ 4/6
⇒ 2/3
$48.865 per headphone
<u>unit rate</u> : total cost/total items
unit rate:
390.92/8
48.865
Each headphone costs $48.865
x=number of oranges.
y=number of bananas.
$5
we can suggest this system of equations:
x+y=12
0.5x+0.25y=5
We can solve this system of equations by substitution method.
x=12-y
0.5(12-y)+0.25y=5
6-0.5y+0.25y=5
-0.25y=5-6
-0.25y=-1
y=-1 /- 0.25=4
x=12-y
x=12-4=8
