We let x be the number of tickets that Sara and Jake sold individually. With this representation, the number of tickets sold by Cole is equal to 2x+6.
(a) x + x + (2x + 6) = 538
The value of x from the generated equation is 133.
(b) Sara sold a total of 133 tickets.
Answer:
The probability is 0.000000207176
Step-by-step explanation:
In this question, we are asked to calculate the probability that if 6 cards are selected from a deck of cards, we will be having 4 kings and 2 queens.
Before we answer, we should understand that in a deck of cards, there are 4 queens and 4 kings. The probability of selecting a king is the same as the probability of selecting a queen which is 4/52 = 1/13
Okay now we want to find the probability of the six cards being 4 kings and 2 queens. Since the probabilities are equal, we proceed to calculate at the same time.
That would be (1/13)^6 = 0.000000207176
The probability of selecting 4 kings and 2 queens is 0.000000207176
X=40
Complementary=90 degrees
50+x=90
-50 -50
X=40
160/4 = p/6
Cross-multiply the propportion:
160 x 6 = 4p
Divide each side by 4:
p = 40 x 6 = 240 pages
