Find the probability that you roll the same number twice in a row when you toss two fair 6-sided dice.

Answer: 6/36

Step-by-step explanation:

When tossing two number cubes, you can get such sample space

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

There are 36 possible outcomes. Only (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6) use the same number twice.

Hence, the probability that you roll two numbers that are the same in a row is 6/36, or in simplified form, 1/6.

Hope that helps! :)

A box contains 3 black pens, 7 blue pens, and 5 red pens. She pulls a red pen, puts it back, pulls a blue pen, puts it back, and
saveliy_v [14]

Answer:

7/25

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = expected outcome/total outcome

If the box contains 3 black pens, 7 blue pens, and 5 red pens, the total number of pens in the box is 3+7+5 = 15pens

Probability of pulling a red pen and replacing = 5/15 = 1/3

Probability of pulling a blue pen and replacing = 7/15

Probability of pulling a black pen and not replacing(using it) = 3/15

{Note that the total number of outcome used will still be 15 since the black pen was pulled out last even though it wasn't replaced.}

P(red, then blue, then black) = 1/3×7/15×3/15

= 63/225

= 7/25

2x+4y=12 y=0.25x-3 What is the solution to the system of equations?
ololo11 [35]
{ 2 x + 4 y = 12
   y = 0.25 x -3

Arrange equation variables of elimination :

{ 2 x + 4 y = 12
 -0.25 x  + y = - 3

Multiply  ( -0.25 x +y = - 3 )  by 8 :

8y - 2 x =  - 24 

{ 2 x + 4y = 12
  -2x + 8y  = -24
----------------------
        12 y = -12

y = - 12 / 12

y = - 1

For x :

2 x  + 4y = 12

2 x + 4 ( - 1 ) = 12

2 x - 4 = 12

2 x = 12 + 4

2 x =  16

x = 16 / 2

x = 8

x = 8 and y = - 1  =>  ( 8 , - 1 )

Answer b

hope this helps!
