Step-by-step explanation:
1/3(12+3x6)-5
Multiply 3 and 6 to get 18.
1/3(12+18)-5
Add 12 and 18 to get 30.
1/3x30-5
Multiply 1/3 and 30 to get 30/3
30/3-5
Divide 30 by 3 to get 10.
10−5
Subtract 5 from 10 to get 5.

if 71 paying passengers are all children, they should pay 5* 71= $355 in total.
$439 is paid so adults pay $439-$355 = $84 more than money paid by same number of children.
each adult pays $8-$5=$3 more than each child
so there are $84/$3= 28adults
and 71-28= 43 children

Step-by-step explanation:
Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.
The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.
The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.
