If you answer all you get 40 points and marked !

1. there are 40 slips in all, green: 15, red: 10, blue: 3, yellow: 12. what is the probability of either getting a green or a blue slip?

2. what is the probability of either getting a green, yellow , or blue slip?

3. what is the probability of either getting a green, red, or blue slip?

P( green or blue) = 9/20

P( green, yellow or blue)  = 3/4

P( green,  red or blue)  = 7/10

Step-by-step explanation:

There are 40 slips in all, Green: 15, Red: 10, Blue: 3, Yellow: 12.

P( green or blue) = green or blue / total

                            = (15 + 3)/ 40

                            = 18/40

                             = 9/20

P( green, yellow or blue) = green yellow or blue / total

                            = (15+12 + 3)/ 40

                            = 30/40

                             = 3/4

P( green, red or blue) = green  red or blue / total

                            = (15+10 + 3)/ 40

                            = 28/40

                             = 7/10

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
