The expected value of:
X = 3 green marbles
Step-by-step explanation:
Number of marbles in a bag = 11
Make-up of the bag = 6 red and 5 green marbles
Sussan selects 7 marbles from the bag
The probability of collecting from 5 of the green marbles = 0.45
The probability of collecting from 6 of the red marbles = 0.55
The expected value of X = the probability of selecting a green marble multiplied by the number of marbles selected
= 0.45 x 7
= 3 green marbles
