If f(x)= -3x + 1, then f^-1(x)=

f^-1(x) = (x-1)/-3

Step-by-step explanation:

Invert equation:

Describe X in original function:

multiplied by -3

add 1

Reverse order:

subtract 1

divide by -3

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
