Answer 2

Answer: $\text{P(draw an blue marble})=\dfrac{12}{20}=\dfrac{3}{5}$

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 :-

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