For the independent events example why does A and B only include the right possible outcomes and not all the possible outcomes? For example, A doesn't have TT & TH.

You said firstly, mutually exclusive is two events, share outcomes and in Extra Example 2, you said they shouldn't share anything in common, how that's even possible?

At 6:30 he lists the sample space of two coin flips as: HH, HT, TH and then say and writes HH again. NO mention of TT. Let's hope I get a response sooner than the post from Michael Sampson that took 3 months.

Probability and Events

  • Mutually exclusive events are events that cannot occur together.

  • Two events are independent if knowing one event’s occurrence does not affect the probability of the other event occurring.

  • The complement of event A is all of the outcomes that are not in event A.
