Protractor The protractor is semicircular in shape. It is
used to measure angles in degrees.
When constructing angles with a pro-
tractor:
a) Draw a line segment and mark points
A and B.

a line segment has two ends so ●●

the dots equal a and b

the dots mean that it comes to an end

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 %
