Answer:
Where 
represent the total pressure and 
the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:
And replacing we got:
Step-by-step explanation:
For this case the partial presure of carbon dioxide is given by:
Where represent the total pressure and 
the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:
And replacing we got:
5 girls, 5 boys...total of 10 students
P(1st pick is a girl) = 5/10 which reduces to 1/2
P(2nd pick is a boy) = 5/9
P (both) = 1/2 * 5/9 = 5/18 <=
1/9 of a yogurt can be bought with 5 pounds.
