There are _____ outcomes in the sample space
3. Determine the number of outcomes in the event. Decide whether the event is a simple event or not.

5. Use the frequency? distribution, which shows the number of American voters? (in millions) according to? age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range
Ages 
Frequency 

18 to 20 
5.8 

21 to 24 
7.8 

25 to 34 
21.8 

35 to 44 
24.7 

45 to 64 
52.2 

65 and over 
27.9 
The probability that a voter chosen at random is in the 18 to 20 years old age range is?
1)probability of selecting the number 595 =1/500
2)the sample space is x: 10<=x<=20 or x:{ 10,11,12,13,14,15,16,17,18,19,20}
There are _11_ outcomes in the sample space
3)
Event B has 4 outcomes
4)
for first digit 9 choices are there ;for middle 4 digits each has 10 choices and for last digit 5 choices
hence total codes=9*10*10*10*10*5=450000
5)
probability that a voter chosen at random is in the 18 to 20 years old age range is
=5.8/(5.8+7.8+21.8+24.7+52.2+27.9)=0.0414
