2. Employees were asked how many times per week they exercised. The frequency table shows the results of the survey. 
# of times exercised per week 0 1 2 3 4 5 6 7 8 
Frequency 5 10 2 9 33 12 15 3 1 

(a) Create a probability distribution table from the frequency table. Round probabilities to the nearest hundredth. Fill in the table below. Calculate the total number of responses. Fill that in the Total column. Then show the division of the frequency by the total. This should be a fraction. Finally, put the answer as a decimal in the P(X) column. Example: ¼ = 0.25 
Use the table to find the probabilities P(X) below. 
(b) P(x<4)= 
(c) P(x=6)= 
(d)P(x>=5)= 

Answer: 
X f Total P(X) = f/t P(X) 
0 5
1 10
2 2
3 9
4 33
5 12
