Data is simply raw facts or figures, like numbers or text, which by themselves don’t mean much. But when processed, they become useful information. Today, we collect huge amounts of data—from simple measurements to complex formats like images, videos, and web content. As the amount of data grows rapidly, data mining techniques help us find useful patterns and insights. For example, banks use data mining to study customer transactions and predict who might be interested in loans, credit cards,

1. Laplace-formule
P(A) = gunstige uitkomsten / totale uitkomsten
Voorbeeld:
In een vaas zitten 10 witte, 12 rode en 18 blauwe knikkers.
Totale uitkomsten = 40
Gunstige voor wit = 10
P(wit) = 10 / 40 = 0,25
2. Somregel
P(A of B) = P(A) + P(B) - P(A en B)
Voorbeeld:
P(niet goedgekeurd) = 392 / 550
P(geen lid coalitie) = 485 / 550
P(niet goedgekeurd én geen lid) = 347 / 550
P(A of B) = 392/550 + 485/550 - 347/550 = 530/550 = 0,9636
3. Complementregel
P(A) = 1 - P(niet A)
Voorbeeld:
P(geen bruikbare sleutel)

What are the two disk storage types supported by Windows Server 2016 and how do they differ? Windows server 2016 supports two essential disk storage types; basic disks and dynamic disks. A basic disk is one that uses traditional disk management techniques and contains primary partitions, extended partitions, and logical drives. A dynamic disk is one that does not use traditional partitioning. Dynamic disks provide more flexibility than basic disks so there is virtually no restriction on the number...
