Geometric or Poisson Drought length is referred to as the number of consecutive time intervals in which the water supply remains below a critical value. Consider the drought length as a random variable, denoted as $Y$...
The geometric distribution is defined as $$P(Y=k)=p(1-p)^{k-1},\quad k\geq 1$$ Equivalently: $$P(Y>k)=(1-p)^k$$ The first question just asks $P(Y=3)$, and the second question asks $P(Y\leq 3)$, which we can write $1-P(Y>3)$.
