Explanation / Answer

Question 6) Solution: We can use here,

P(A OR B) = P(A) + P(B) – P(A AND B)

Probability of getting challenge that was made by a male player or not rejected.

P[a male player or not rejected]

=P[male player] + P[not rejected] - P[a male player and not rejected]

=489/839+327/839-201/839

=615/839

=0.7330

Option b) is correct.

Question 10) Solution:

Probability of selecting someone who was sentenced to prison or plea of guilty.

P[selecting someone who was sentenced to prison or plea of guilty]

=P[selecting someone who was sentenced to prison ]+P[plea of guilty]-P[selecting someone who was sentenced to prison and plea of guilty]

=278/881+649/881-193/881

=734/881

=0.8331

Option d) is correct.
