A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random.

DerKrebs [107]

corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color c)the marbles are different in color

Answer:

Step-by-step explanation:

The probability was done with replacement.

Probaility of an event happening $=\frac{number of required outcomes}{number of possible outcomes}$

number of blue marbles= 2

number of green marbles=5

total number of marbles=7

(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)

$=\frac{2}{7}*\frac{2}{7}$

$=\frac{4}{49}$

(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)

$=\frac{4}{49} + \frac{5}{7}*\frac{5}{7}$

$=\frac{4}{49} + \frac{25}{49}$

$=\frac{29}{49}$

(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)

$=\frac{2}{7}*\frac{5}{7}+ \frac{5}{7}*\frac{2}{7}$

$=\frac{10}{49}+\frac{10}{49}$

$=\frac{20}{49}$

Answer:

Step-by-step explanation:

15. (-4-3)/(-5-0)= -7/-5= 7/5

y - 3 = 7/5x - 0

y = 7/5x + 3

16. (-2-3)/(4-0)= -5/4

y - 3 = -5/4x - 0

y = -5/4x + 3

17. (-3+5)/(0+3)= 2/3

y + 5 = 2/3(x + 3)

y + 5 = 2/3x + 2

y = 2/3x - 3

18. (-2-2)/(0+4)= -4/4= -1

y - 2 = -1(x + 4)

y - 2 = -x - 4

y = -x - 2

19. y - 3 = 1/2x - 0

y = 1/2x + 3

20. y - 2 = -(x + 1)

y - 2 = -x - 1

y = -x + 1

21. perp. -5/3

y + 5 = -5/3x + 0

y = -5/3x - 5

22. perp. 1/2

y + 1 = 1/2(x + 4)

y + 1 = 1/2x + 2

y = 1/2x + 1

23. perp. 3/4

y + 5 = 3/4(x + 4)

y + 5 = 3/4x + 3

y = 3/4x - 2

24. perp. 7/5

y - 4 = 7/5(x - 5)

y - 4 = 7/5x - 7

y = 7/5x - 3
