Answer:
The probability of getting someone who is age 18-22 or does not smoke is 0.854 ....
Step-by-step explanation:
Through the given statements we have to find the probability of getting someone who is age 18-22 or does not smoke.
Age 18-22 has 177 people. 48 of whom smoke.
People who does not smoke =(177-48) + (146-31) +(81-28)
People who does not smoke=129+115+53 = 297
People with age (18-22) who does not smoke = 129
P(18-22 or does not smoke) = (177+297-129)/(177+146+81)
P(18-22 or does not smoke) = 345/404
P(18-22 or does not smoke) = 0.854
Thus the probability of getting someone who is age 18-22 or does not smoke is 0.854 ....
Answer:
Step-by-step explanation
First You found that number
First we will find the number of integers between 301 and 400 that are multiples of 4. We can see that the first such number is 304 being a multiple of 4. So the required numbers are 304, 308, 312,...,400 which form an AP.
To find the number of such integers use,
. Here 
is the nth term, 
is the common difference of the AP. Here its is 
. So
The required sum of the AP is
