Suppose in an event of fire, the probability is 95% that fire alarm will ring in a building. let x denote the number of fire alarm that will ring in case of fire. suppose there are 3 fire alarms. a) write the probability distribution of x. b) explain x=0, x=1, x=2 and x=3 b) draw a tree diagram for this problem. e) what is the probability that i) exactly 2 alarm will ring ii) at least 2 alarm will ring iii) at most 2 alarm will ring iv) all 3 alarm will ring. anyone me
