Probability of the event not happening = 0.3

Explanation:

Probability of an event happening #p=0.7#
Probability of the event not happening = ?

Probability of an event happening + Probability of the event not happening #=1#

Probability of the event not happening# = 1 - #Probability of an event happening #=1-0.7=0.3#
