Number of times exercised per week

0 1 2 3 4 5 6 7 8

 

Frequency

Create a probability distribution table from the frequency table. Round probabilities to the nearest hundredth.

5 + 10 + 2 + 9 + 33 + 12 + 15 + 3 + 1  = 90

 

0 times  =  5/90 = .06

1 time  = 10/90 = .11

2 times = 2/90 = .02

3 times = 9/90 =  .1

4 times =  33/90 = .37

5 times = .12/90 = .13

6 times = 15/90 = .17

7 times = 3/90 = .03

8 times = 1/90 = .01

Thank you so much! I've been having a lot of trouble with this concept.

Just sum the frequencies.....then....divide each frequency by this sum to get each %
