Karen designs a number generator that produces the integers 0 to 4. She then runs the generator 500 times.
The results are shown in the table below. Use the table below to answer each of the questions below,
showing all your work for full credit.
Integer
Frequency
0 49
1 74
2 104
3 121
4 152
(a) If Karen runs the generator a total of 3,000 times, what is the expected number of times the integer 2
is produced?
(b) What inference can be made about how often occurs compared to the rest of the numbers? Explain
using at least one sentence.
