Question: There were 6 marbles in a bag four were red two were blue what is the probability that you will pull out a blue marble
Answer:
Pr(blue) = 1/3
Step-by-step explanation:
From the question,
Probability = Possible outcome/Total outcome
Pr(blue) = number of blue marbles(B)/Total number of marbles
Pr(blue) = B/N.................... Equation 1
Where B = Total number of blue marbles, n = Total number of marbles
Given: B = 2, n = 6
Substitute these values into equation 1
Pr(blue) = 2/6
Pr(blue) = 1/3.
Hence the probability that a blue marble will be pulled out is 1/3
