Acircle is defined by the equation given below.
x2 + y2 –x- 2y - 11/4 = 0
what are the coordinates for the center of the circle and the length of the radius?
á (-1/2,-1), 4 units
b. (1/2,1), 4 units
c. (1/2,1), 2 units
d. (-1/2,-1), 2 units

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 %  

step-by-step explanation:

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
