    • Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes’ relative likelihoods and distributions.
    • Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
    • Relative Frequency Definition.
    • Subjective Probability.
    there are 16 socks in the drawer
    probability of 2 white socks  or  2 black socks
    6/16 *5/15  + 10/16*9/15   no replacement on socks
    30/240 + 90/240
    1/2 = 50%
