There are 4 blue and 5 white marbles in a bag. what is the probability of randomly picking a white marble?

Facts:

Step-by-step explanation:

What is the probability of picking a white marble?

The answer is chance. {fraction form}

The answer is 0.555555... chance. {decimal form}

The answer is 55.56% chance. {percent form, rounded}

How did we get ?

We got because there are nine total marbles, and of those nine marbles, 5 of them were white. To calculate probability, you must find the total [of something, in this case, marbles] and then take value [white marbles] you want to find the probability of, and put it over the total as a fraction.

Like this:

5   --->   white marbles

9   --->           total

That is your answer!

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)
