Answer:
Probability of getting blue = [tex]\frac{2}{3}[/tex].
Step-by-step explanation:
Given : A bag contains only red marbles and blue marbles. there are 6 marbles in the bag. the bag contains twice as many blue marbles as red marbles. nadia takes one marble from the bag without looking.
To find : the probability that the marble is blue .
Solution : We have given
Total marble in beg = 6
Let the red marble = x
Blue = 2x .
So, x + 2x = 6.
3x = 6
On subtracting both sides by 3
x = 2.
Red marble = 2
Blue marbles are 4.
Probability of getting blue = [tex]\frac{Blue\ marble}{Total\ marble}[/tex].
Probability of getting blue = [tex]\frac{4}{6}[/tex].
Probability of getting blue = [tex]\frac{2}{3}[/tex].
Therefore, Probability of getting blue = [tex]\frac{2}{3}[/tex].
