Answer:

0.5021 or about 50%

Step-by-step explanation:

chance of getting heads is 1 out of 2 =1/2

chance of getting 1or 6 is 2 out of 6 = 2/6

1/2 * 2/6= 2/12 reduced to   1/6

each turn you have a 1 0ut of 6 chance of winning

16% chance of winning so an 84% chance of losing

chance of losing  4 times is .84 ^4  =0.4979

chance of winning  is 1-(.84^4)= 0.5021

dmitriy555 [2]

Answer:

Chris earned $ 43,344 each year

Monthly Chris earns $ 3,612

Step-by-step explanation:

If you earn a fixed amount of money each month, for 2 years and one year you have 12 months, then 2 years equals 24 months.

To know how much you earn each month we divide the total amount earned in the two years between 24 months

I = $ 86,688 / 24

I = $ 3,612

Monthly Chris earns $ 3,612


To calculate what he earned each year we divided $ 86,688 / 2

I = $ 86,688 / 2

I = $ 43,344

Chris earned $ 43,344 each year

Can some please answer this
Sonbull [250]

9514 1404 393

Answer:

  B  (2 violet)

Step-by-step explanation:

Let the colors be represented by their first letter. Then the balances give rise to two equation:

  o +y +b +v = r +g +b

  o +y +v = g +v

Subtracting the second equation from the first gives ...

  (o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)

  b = r +b -v

Adding v-b to both sides, we have ...

  b +(v -b) = r +b -v +(v -b)

  v = r

Multiplying this result by 2, we can match the final balance:

  2r = 2v . . . . . . . choice B
