g A survey asked households whether they have a cell phone, a personal computer, or a television. If 40 had a cell phone 60 had a personal computer 50 had a television 25 had a cell phone and a personal computer 30 had a personal computer and a television 35 had a cell phone and a television 10 had all three how many households had at least one of the three devices

A survey is a research method used for collecting data and then analyse.

The number of households that had at least one of the three devices is 70.

According to question,

Since, 40 had a cell phone,

60 had a personal computer

50 had a television

25 had a cell phone and a personal computer n (C ∩ PC) = 25

30 had a personal computer and a television ,n(PC ∩ T) = 30

35 had a cell phone and a television , n (C ∩ T) = 35

10 had all three ,n (C ∩ PC ∩ T) = 10

We know that,

Therefore,  70 households that had at least one of the three devices.

The number of households that had at least one of the three devices is 70.

Step-by-step explanation:

The data provided is as follows:

n (C) = 40

n (PC) = 60

n (T) = 50

n (C ∩ PC) = 25

n (PC ∩ T) = 30

n (C ∩ T) = 35

n (C ∩ PC ∩ T) = 10

Compute the number of households that had at least one of the three devices as follows:

Thus, the number of households that had at least one of the three devices is 70.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
