Answer:
a) 31% b) 48% c) 31%
Explanation:
We have the probabilities:
P(had TV) = 0.52
P(had refrigerator)=0.38
P(had both a TV and a refrigerator)=0.21
<em>a) a TV but no refrigerator </em>
P(a TV but no refrigerator) =P(TV)- P(both a TV and a refrigerator) = 0.52 - 0.21 = 0.31
<em>(b) a TV or refrigerator but not both </em>
P(a TV or refrigerator but not both) = P(TV) + P(had refrigerator) - 2×P(had both a TV and a refrigerator) = 0.52+ 0.38 - (2×0.21) = 0.48
<em>(c) neither a TV nor a refrigerator</em>
P(neither a TV nor a refrigerator) = 1 - ( P(TV) + P(had refrigerator) - P(had both a TV and a refrigerator) ) = 1- (0.52 + 0.38 - 0.21) = 0.31

The answer to the question above is ntuser.dat. This is actually a registry file that contains the registry information of the user or account. According to Windows, this is known to be as the <span>"central hierarchical database" as this contains relevant information of the user such as profiles, and both of its hardware and software.</span>
There are two common types for data access or retrieval
1. Sequential access is the main access mode only in batch systems, whereas files are used and updated at regular intervals.
2. Direct access - on-line processing requires direct access, whereby a record can be accessed without accessing the records between it and beginning of the file.
You have a raspberry pi connected to all the sensors and a code running to trigger if the sensors are triggered. Each sensor and keypad would run to a different input on the pi. They should al be able to be powered with a single cell lipo. Is that what you are asking?
