You randomly draw a marble out of a bag that contains 20 marbles. 12 of the marbles in the bag are blue. What is [tex]\text{P(draw a blue marble)}[/tex]?

Answer :

Answer: [tex]\text{P(draw an blue marble})=\dfrac{12}{20}=\dfrac{3}{5}[/tex]

Step-by-step explanation:

Given: The total number of marbles in a bag = 20

The number of blue marbles in the bag = 12

Then, the probability of drawing a blue marble is given by :-

[tex]\text{P(draw a blue marble)}=\dfrac{\text{Number of blue marbles}}{\text{Total marbles}}\\\\\Rightarrow\text{P(draw an blue marble})=\dfrac{12}{20}=\dfrac{3}{5}[/tex]
