    Answer:Pr (A or B) = 2/3

    Step-by-step explanation:

    Pr (rolling a 2) = 1/6 ... let this be A

    Pr (getting a head) = 1/2 ... let this be B

    Pr (A or B) = 1/6 + 1/2

    =4/6

    Pr (A or B) = 2/3

    2/3

    Step-by-step explanation:

    P1 = rolling 2 = 1/6

    P2 = heads = 1/2

    P1 OR P2 = P1 + P2 = 1/6 + 1/2 = 4/6 = 2/3
