    Answer:

    -1 (losing a point)

    Step-by-step explanation:

    it is a probability question

    total possible outcomes= 3

    favourable outcome(white) = 2

    probability of getting a white is 2/3

    probability of getting a green is 1/3

    so the expected value of the game will be -1
