Answer:
first person has a chance of 7/28 or 1/4
The second = 6/27 or 2/9
The third = 5/26
And the fourth = 4/25
multiplying these together you get 4 / 2340=
1/585
or 0.17%
9x-9y=-9
x-y=-9/9
x-y+1=0.......(1)
4x-3y=-8
4x-3y+8=0....(2)
combining equation we get
(x-y+1)(4x-3y+8)=0
x(4x-3y+8)-y(4x-3y+8)+4x-3y+8=0
4x²-3xy+8x-4xy+3y²-8y+4x-3y+8=0
<u>4x²+3y²-7xy+12x-11y+8=0</u><u> </u><u>is</u><u> </u><u>your</u><u> </u><u>equation</u><u>.</u>
Its b hope it helps good luck
it's quite simple. all you need too do is add the total amount then divide
group A (box one) =(0.85). Group A (directly under the first one) =(0.15). Group B do 34 + 14 to get 48 then you divide 34÷48 to get (0.71) that is your answer to the first box in Group B then you do the exact same thing as you did in the first one, but swich 14 for 34 and you will get (0.29)
Simplified to make it easier to read.
Group 1. (0.85 0.71)
Group 2. (0.15 0.29)
