- X + 3Y = 2 (*)
⇔X = 2 - 3Y (1)
- Y = 2X + 3 (2)
(1),(2)⇒ Y = 2(2 - 3Y) +3
⇔ Y = 4 - 6Y + 3
⇔ Y = 1 (**)
(*),(**)⇒ X + 3×1 =2
⇔ X = -1
Probability of green die being even: 3/6, which simplifies to 1/2 (2, 4, 6 are even and 1, 3, 5 are odd)
Probability of blue die being even: 3/6, which simplifies to 1/2.
Compound probability:
1/2* 1/2= 1/4
Final answer: 1/4
Hey You!
Tom:
22*7% = 1.54
His Cousin:
18*7% = 1.26
22 + 1.54 = 23.54
18 + 1.26 = 19.26
So, Tom pays $23.54 and His Cousin pays $19.26 and Tom payed more tax.
