10/13
Step-by-step explanation:
There are 52 cards in a standard deck. There are 4 queens (queen of spades, clubs, hearts, diamonds) and 36 (2 - 10 of four suites) number cards. Therefore the probability of drawing a queen or a number card is (4 + 36)/52 = 40/52 = 10/13.

Answer:
7 hours
Step-by-step explanation:
We have that the value of the review of a bicycle has the following function:
v = 14 + 9 * t
where t is the time in hours
if we know that Aara paid a total of 77, that is v = 77, we can calculate the value of t, replacing:
77 = 14 + 9 * t
solving for t:
t = (77 - 14) / 9
t = 7
that is to say that Sara left the bicycle in a total of 7 hours
