Probability is simply how likely something is to happen.
Probability of getting 2 red marble is [tex]\frac{36}{121}[/tex]
Number of blue marble = 5
Number of red marbles = 6
Total number of marbles = 5 + 6 = 11
Since, probability is calculated by dividing the favorable number of outcomes by the total number of possible outcomes.
Probability of getting one red marble = [tex]\frac{6}{11}[/tex]
Since, A marble is taken at random from the bag, the colour is noted and then it is replaced.
Therefore, probability of getting 2 reds marble = [tex]\frac{6}{11}*\frac{6}{11}=\frac{36}{121}[/tex]
