Question 1038391: You conduct another survey of 117 residents about whether they want trash pickup, recycling pickup, or basic cable as part of their HOA fees. The following data was collected:
54 residents want trash pickup.
43 residents want recycling pickup.
54 residents want cable.
15 residents want both trash pickup and recycling pickup.
24 residents want both trash pickup and cable.
18 residents want both recycling pickup and cable.
5 residents want all three.
What is the probability that a randomly chosen resident would want none of the services as part of their HOA fees?
Round your answer to 2 decimal places as needed.
c) What is the probability that a randomly chosen resident would want trash pickup, but not recycling pickup as part of their HOA fees??
Round your answer to 2 decimal places as needed.
d) What is the probability that a randomly chosen resident would want cable & trash pickup or would want trash pickup & recycling pickup?
You can put this solution on YOUR website!
TR&C given as 5. T&R given as 15, but that includes the TR&C, so T&R only is 10. Likewise, R&C only is 13 and T&C only is 19.
T only is 54, but that includes TR&C, T&C, and T&R so T only is 54 minus 5 minus 19 minus 10 equals 20
Likewise, R only is 43 - 5 - 10 - 13 = 15
And C only is 54 - 5 - 13 - 19 = 17
T only plus R only plus C only plus T&C only plus T&R only plus R&C only plus TRC = 99 that want something out of 117 residents leaving 8 that want nothing so
P(want nothing) = 18/117
One question per post please.
