    Answer:

    I hope this helps <3

    Step-by-step explanation:

    What’s the probability of getting heads on the second toss given that the first toss was a head. (Trying to refresh my probability a bit). I’ve seen this analyzed like this:

    HH 1/4

    HT 1/4

    TH 1/4

    TT 1/4

    So since we are given information (Head on first flip), then TT goes away and were are left with:

    HH 1/3

    HT 1/3

    TH 1/3

    So we could say that HH now has a 1/3 probability. Should we not also get rid of TH, since we know that the first flip is a head? So now we have:

    HH 1/2

    HT 1/2
