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!

easy math just plug in a and b
