Answer:
a) 0.25
b) 0.38
c) 0.12
d) 0.64
Step-by-step explanation:
We have these following informations.
There are 500 people between 18 and 29. Of those 190 have at least one tattoo and 310 have no tattoo.
There are also 500 people between 30 and 50. Of those, 60 have at least one tattoo and 440 have no tattoo.
a) P(tattoo)
There are 1000 people. Of those, 190+60 = 250 have tattoo. So P(tattoo) = 250/1000 = 0.25.
b) P(tattoo|age 18-29)
There are 500 people aged 18-29. Of those, 190 have at least one tattoo. So P(tattoo|age 18-29) = 190/500 = 0.38.
c) P(tattoo|age 30-50)
There are 500 people aged 18-29. Of those, 60 have at least one tattoo. So P(tattoo|age 30-50) = 60/500 = 0.12.
d) P(age 18-29|tattoo)
250 people have at least one tattoo. Of those, 160 are between 18 and 29. So P(age 18-29|tattoo) = 160/250 = 0.64.
Answer:
Step-by-step explanation:
d=13-7=6
Let number of terms=n
l=a+(n-1)d
601=7+(n-1)6
601=7+6n-6
601=6n+1
6n=601-1=600
n=600/6=100
The answer is C. Thats the measure
