50% of babies are born female. Olive wants to find the probability that 20 or more of the 50 babies born today
were female.
We need to design a simulation. Which random device can we use to
BEST represent this situation?
Use a pair of dice and assign
doubles as female and
everything else as male.
Use a double-sided coin and
assign heads as females and
tails as males.
Use a random number generator
with the numbers 1 through 100
and assign 1 through 20 as
female and 21 through 100 as
male.
Use a spinner with 50 parts
and assign 20 parts as female
and 30 parts as male.

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
