    The probability of one head and one tail is 2/3.

    Step-by-step explanation:

    The possibilities for flipping two fair coins are {T, T}, {H, H}, {H, T}, {T, H} Given the case that at least one coin lands on a head, So the total possibilities are {H, H}, {H, T}, {T, H} = 3 possibilities Required event is 1 head and 1 tail = {H, T}, {T, H} = 2 possibilities

    To calculate the probability of one head and one tail,

    Probability = required events / Total events

    Probability = 2/3
