Jared has a bag that contains 8 blue marbles, 6 red marbles, and 10 green marbles. he selects a marble, replaces it in the bag, and then selects another marble. what is the probability that both marbles are green? fraction form

Total marbles = 8 + 6 +10 = 24

The probability of picking a green would be 10/24, which reduces to 5/12.

Since they put the first marble back, the probability of picking another green one would be the same as the first time, 5/12.

The probability of picking green twice would be 5/12 x 5/12 = 25/144

\frac{25}{144}[/tex]

All the probabilities will be written as fractions, and all the denominators will be the same, because all the marbles are together. The denominator will be equal to the sum of all marbles in the bag:

6 + 8 + 10 = 24

= probability of getting a blue marble

= probability of getting a red marble

= probability of getting a green marble

Now, the final probability. The probability of both marbles selected being green, will be represented by a multiplication,

Hope it helped,

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841

a is the right answer
