Question

in a bag of containing 32 white marbels, 18 blue marbels and 10 red marbels , if it take one randomly , change of getting the blue marbels is

Answer 1

18/60 which is equal to 3/10

So you just need to put it into proportions which is blue to total. The total is 60 and there is 18 blue. Then you only need to simplify.

Answer 2

Change or chance?

To find the probability/chance of getting the blue marbles is:-

$probability = \frac{number \: of \: blue \: marbles}{total \: of \: all \: marbles}$

From the question, we have:-
Number of blue marbles : 18
Total of all marbles : 32 + 18 + 10 = 60

Thus,
$probability = \frac{18}{60} \\ probability = \frac{3}{10}$
