The probability of having a boy: 1/2
1/2(1/2)(1/2)=1/8
The probability of a family having three boys is 1/8.
Hope this helps!
Assume that,
adult = x
child = y
x+2y = 35 (1st equation)
2x+3y = 60 (2nd equation)
x = 35-2y (3rd equation)
Substitute 3 into 2 :
2(35-2y) + 3y =60
70-4y +3y = 60
y = 10
x+2y = 35
x+2(10) =35
x +20 =35
x = 15
One adult = $15
Y=9x because if you divided y by x all the numbers will equal to 9 which is proportional
