If the probability of getting struck by lighting each year is 1 in 1,000,000, what is the probability that you will not be struck by lightning in one year?
Our sample space is either getting struck by lightning or NOT getting struck by lightning. So we have:
P(Not getting struck by lightning) = 1 - P(Getting struck by lightning)
P(Not getting struck by lightning) = 1 - 1/1,000,000
P(Not getting struck by lightning) = 999,999/1,000,000
