Response:
1/6
Detailed explanation:
Let
c -----> the count of cola bottles chosen by Dan
s -----> the count of smarties selected by Dan
m -----> the count of marshmallows selected by Dan
we have
c=3s -----> A equation
m=2s -----> B equation
we understand that
To determine the fraction of the sweet bag that consists of smarties, we must divide the number of smarties by the total amount of sweets
The overall number of sweets is calculated as
(c+s+m)
substituting equations A and B into the total sweets
(3s+s+2s) =6s
Calculate the fraction
s/6s
Reduce it
1/6
For the first film he may pick any of 6 options; once that choice is made, 5 remain for the second, then 4 for the third, and so forth.
Hence the total is 6! = 6*5*4*3*2 = 720 possible orders
