On a biased dice the probability of getting 1 is 0.3. The ice is rolled 150 times. How many ones would you expect to roll?

  1. Answer:  45

    =====================================================

    Work Shown:

    n = number of rolls = 150

    p = probability of rolling a “1” = 0.3

    n*p = expected number of “1”s that show up out of the 150 rolls

    n*p = 150*0.3

    n*p = 45

    We expect about 45 ones will show up.
