Question

If p is equal to 0.05 what is the probability of not e

Answer 1

p(not e)=1 -p(e)

=1-0.05

=0.95

Answer 2

P(E) = 0.05

P( Not E ) = ?

P(Not E ) = 1 - P(E)

= 1 - 0.05

= 0.95

• The sum of probablity of all the event is 1.
• The probability of an event cannot be greater than 1 and equal to 0.
• The probablity of an impossible event is 0.
• The probablity of sure event is 1.
