STAT 270 Lecture Notes - Lecture 19: Poisson Distribution

Make a probability distribution for the given set of events. The sums that appear when two fair four-sided dice (tetrahedrons) with sides 1, 2, 3, and 4 are tossed. Complete the probability distribution below.

The data represent the number of customers waiting for a table at 7 pm for 40 consecutive Saturdays.

9,9,8,9,4,9,11,6,

13,10,6,8,4,7,5,10,

10,11,8,3,6,7,6,10,

13,11,12,6,10,7,9,10,

9,9,8,9,4,9,11,6.

Fill this table for absolute and relative frequencies.

A die is weighted in such a way that each of 2,4, and 6 is twice as likely to come up as each of 1, 3 and 5.

Find the probability distribution. What is the probability of rolling less than 4? [Hint: See Example 3].
