Question

a jar has 6 green 4 red 5 yellow and 5 blue Marbles what is the probability of getting a green marble

Answer 1

Total marble =6+4+5+5=20
Possiblity of getting green =6/20=0.3

Answer 2

Answer :

➡ What's probability ?

Probability is the way of finding how likely an even gonna occur.

We find probability of a given event by the given formula :

$Probability = \frac{favourble \: outcome}{total \: outcome}$

Favourable outcome : The result we get after a certain assumption.

Total outcome : The possible number of event that could occur.

For example: The probability of getting 1 when a dice is rolled is 1/6.

Reason : There are total 6 face of a dice and the favourable outcome i.e., 1 could come only once so we get the probability as 1/6.

Now, the probability of getting a green marble :

$Probability = \frac{favourble \: outcome}{total \: outcome}$

$Probability = \frac{6 }{6 + 4 + 5 + 5}$

$Probability = \frac{6}{20} = \frac{3}{10}$
