Given the complex number z1 = 24√3(cos(7π/6)+i sin(7π/6)) and z2 = 4( cos(2π/3)+ i sin(2π/3)), express the result of z1/z2 in rectangular form with fully simplified fractions and radicals.

Afootball quarterback has two more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 25% of the time. when his first throw is incomplete, he misses the receiver on the second throw 15% of the time. what is the probability of not throwing the ball to a receiver on either throw?
