Sagot :
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%
