Answer to Question #167849 in Statistics and Probability for Preetika Gurung

Question

Suppose a fire broke out and you are trapped at your home. You send out three messages 

for help. An SMS at your friend’s mobile phone that has the probability of 0.1 of being 

seen; a message wrapped in a stone and thrown outside that has the probability 0.2 of being 

found; and a shout for help that has probability 0.3 of being heard. Find the probability that 

you are saved, assuming that the three ways are independent.

Answer 1

If you send all of these three messages, the probability that you are saved will be 0.1 + 0.2 + 0.3 = 0.6
