    P (X > 5) = 72,2 %

    Step-by-step explanation:

    The probability of success (outcomes bigger than 5)

    If dice 1 outcome is 6 no matter wich outcome we get from dice 2 all events are successful, the we have 6 outcomes

    If dice 1 outcome is 5 we also have 6 outcomes

    If dice 1 outcomes is 4 we have 5 positive outcomes

    If dice 1 outcome is 3 we have 4 positive outcomes

    If dice 1 outcome is 2 we have 3 positive outcomes

    if dice 1 outcome is 1 we have 2 positive outcomes

    Total evaluating dice 1: positive outcomes 26

    We will get the sames results analysing dice 2 then we have a total of

    52 successful events

    And total numbers of outcomes is 36 + 36 = 72

    Then

    P (X > 5) = 52/72

    P (X > 5) = 0,722

    P (X > 5) = 72,2 %
