You have 6 Rolls Royces and 7 Lamborginis in your (rather large) garage. Every morn- ing, because variety is the spice of life, you choose one completely at random to drive around that day. What is the probability that in the course of a week (7 days) you choose Lamborginis exactly 5 times? (A) 2(7/13)*(6/13)² (B) 1287(6/13)*(7/13)² (C) 1287(7/13)*(6/13)? (D) 5(6/13)°(7/13)² (E) 21(6/13)*(7/13)² (F) 5(7/13)*(6/13)² (G) 2(6/13)°(7/13)? (H) 21(7/13)°(6/13)²

You have 6 Rolls Royces and 7 Lamborginis in your (rather large) garage. Every morn-
ing, because variety is the spice of life, you choose one completely at random to drive
around that day. What is the probability that in the course of a week (7 days) you
choose Lamborginis exactly 5 times?
(A) 2(7/13) (6/13)2
(B) 1287(6/13)*(7/13)2
(C) 1287(7/13) (6/13)2
(D) 5(6/13)°(7/13)?
(E) 21(6/13)*(7/13)2
(F) 5(7/13) (6/13)2
(G) 2(6/13)*(7/13)²
(H) 21(7/13)*(6/13)²
