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? September 2, 2021 by Yến Oanh 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?
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. Reply
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.
