If A denotes some event what does A denote If PAequals0997 w

If A denotes some event, what does A denote? If P(A)equals=0.997, what is the value of P(A)? If P(A)equals=0.997, is A unusual?

Solution

Sol)

P(not A)=0.003 (1-0.997=0.003) P(not A) , meaning that compliment of A consists of all outcomes(results) in which event A does not occur. It is not unusual(only outcomes <0.05 are unusual).
