Answer:

A straightforward question but good because it provides a good framework for understanding and applying probability.

There are:

3 red marbles,

7 green marbles and

10 white marbles

A total of 20 Marbles.

Therefore the Probability of a white marble is:

P (white) =

(The number of white marbles) / (The total number of marbles)

which equals

(10)/(20)

= 1/2

= 0.500

= 50%

So P(white marble) = 0.5 = 50%

Answer:

There are:

3 red marbles,

7 green marbles and

10 white marbles

A total of 20 Marbles.

Therefore the Probability of a white marble is:

P (white) =

(The number of white marbles) / (The total number of marbles)

which equals

(10)/(20)

= 1/2

= 0.500

= 50%
