## Probability and statistics symbols

Probability and statistics symbols table   Symbol Symbol Name Meaning / definition Example P(A) probability function probability of event A P(A) = 0.5 P(A ∩ B) probability of events intersection probability that of events A and B P(A∩B) = 0.5 P(A ∪ B) probability of events union probability that of events A or B P(A∪B) = 0.5 P(A | B) conditional probability function probability of event A given event B occured P(A | B) =…

## Number System

b – numeral system base dn – the n-th digit n – can start from negative number if the number has a fraction part. N+1 – the number of digits Binary Numeral System – Base-2 Binary numbers uses only 0 and 1 digits. B denotes binary prefix. Examples: 101012 = 10101B = 1×24+0×23+1×22+0×21+1×20 = 16+4+1= 21 101112 = 10111B = 1×24+0×23+1×22+1×21+1×20 = 16+4+2+1= 23 1000112 = 100011B = 1×25+0×24+0×23+0×22+1×21+1×20=32+2+1= 35 Octal Numeral System – Base-8…
