Probability is simply how likely something is to happen.

Probability of getting 2 red marble is  

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 =

Since, A marble is taken at random from the bag, the colour is noted and then it is replaced.

Step-by-step explanation:

There are 6 red marbles out of total 11.

The probability of drswing two red marbles is 6/11 x 6x11 = 36/121

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
