If my diameter is 19 inches, what is my radius?

9.5inches

Step-by-step explanation:

Radius r = diameter(d) /2

Given diameter of 19inches

r = 19/2

r = 9.5 inches

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

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 %
