A string of lights contains three lights. the lights are wired in series, so that if any light fails the whole string will go da

vazorg [7]

Let $p_i=0.1$ be a probability that i-th light fails, where i=1,2,3. Then, $q_i=1-p_i=1-0.1=0.9$ is the probability that i-th light remain bright.
If the lights fail independently of each other, the probability that a string of lights will remain bright for two years is:


$q_1q_2q_3=(0.9)^3=0.729$ .
