    Question A toss of one fair 12 sided die

    Hi Everyone,

    I've been working on this problem but am unsure if I am doing it correctly. Please take a look.

    Toss one fair 12 sided die

    a) What is the sample space of all possible outcomes of one toss?
    b) Let’s define event A as “even number appears”. What is the probability of event A?
    c) Let’s define event B as “number smaller than 7 appears”. What is the probability of event B?
    d) Let’s define event C as “number 12 appears”. What is the probability of event C?
    e) What is the complement of event C and what is its probability?
    f) What is the intersection of event A and event B and what is its probability?
    g) What is the union of event A and event B and what is its probability?
    h) Among events A, B, and C, identify a pair of mutually exclusive events.
    i) Compute P(B  C)?
    j) Are events A and B independent? Why?
