5/78 chance to get a Nickel and then a penny without replacing
Step-by-step explanation:
The bag contains a total of 40 coins which show that the probability of getting a Nickel is 5/40 and the probability of getting a penny after taking out a nickel is 20/39. In order to find the Probability of two events together you must multiply the probabilities so
(5/40) * (20/39) = 100/1560 = 5/78
P (Jack) = 4 / 52 = 1/13
P(Queen) = 4/52 =1/13
P(jack or queen) = 1/13 + 1/13 = 2/13
