(a) Find the Sample Space associated with this experiment. (b) Find the event, E , that an even number is rolled. (c) Find the P (E ). 40. Gabe has $2,500 in credit card debt on a card that charges 19.6% per year compounded monthly on the unpaid balance. If he
pays the minimum payment of $50 each month, and he doesn’t use it to make any more purchases, how long will it take Gabe
to pay oﬀ his debt? 41. An experiment consists of rolling a pair of fair sixsided dice. What is the probability that the sum is at least 9 or exactly one
5 is rolled? 42. An experiment consists of randomly selecting 1 marble from a bowl containing 5 red, 3 blue, and 10 white marbles. What is
the probability that the marble selected is not white? 43. Solve the systems of linear equation using the GaussJordan elimination method.
(a)
−12x − 42y − 48z = −114
2x + 7y + 8z = 19
3x + 2y + 10z = 9 9 ...
