Answer #1

a) As we have 2 green balls and 6 yellow balls here, therefore the sample space here would be given as:

{ G1, G2, Y1, Y2, Y3, Y4, Y5, Y6 }

b) Probability that a green ball is selected is computed here as:

P(G) = 2 / 8 because 2 of the 8 balls are green

P(G) = 1/4

c) First we compute here:

P(E) = 4 / 8 as 4 of the 8 balls are even numbered

P(E) = 0.5

Also P(G and E) = 1 / 8 as there is one even numbered green ball

Now computing the required probability using bayes theorem, we get here:

P( G | E) = P(G and E) / P(E) = (1/8) / 0.5 = (2/8) =1 / 4

P(G | E) = 0.25

d) The required probability here is already computed in previous part as:

P(G \cap E) = P(G and E) = 1 /8

P(G \cap E) = 1/8

e) The required probability here is computed using addition law as:

P(G \cup E) = P(G) + P(E) - P(G \cap E)

P(G \cup E) = (2/8) + (4/8) - (1/8)

P(G \cup E) = 5/8

f) Here as we know that P(G and E) is not equal to 0, therefore G and E are not mutually exclusive
