what is the proability that at least one ture pops in the ne

what is the proability that at least one ture pops in the next 5 years

Solution

Since the value of probability is not given, i am assuming it as a variable p

Probability that tures pop in a year = p

Probability that ture doesn\'t pop in a year = (1-p)

Probability that atleast one ture pops in the next 5 years = 1 - P(no ture pops in the next 5 years)

=> 1 - (1-p)^5
