    Answer:

      60

    Step-by-step explanation:

    4 of the 6 numbers on a number cube are greater than 2, so the theoretical probability of a number greater than 2 is 4/6 = 2/3. We expect 2/3 of the 90 die rolls to be greater than 2:

      2/3 × 90 = 60

    We predict 60 die rolls will land on a number greater than 2.
