We can do this using the binomial probability distribution:
5C2 * (1/2)^2 * (1/2)^3 = 10 * 1/32
= 5/16
difference= 0.78[Anastasia's] - (1 - 0.34)[Sergei's]=
0.78m - (0.66m)=0.12m=12cm
First, you want to find the price per pencil:
2.16/12=0.18
Then divide $4.50 by price per pencil:
4.50/0.18=25
He could buy 25 pencils with $4.50.
