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

Hello, there are a few things you need to know in order to solve this problem.

Prerequisite

Probability Trees

Binomial Probability Distribution.

Commutative Binomial Probability  

a) Write the probability distribution of x.

There are a few ways you can go about doing this.

 View first picture.

b) Explain x=0, x=1, x=2 and x=3

   View second picture

c) Draw a tree diagram for this problem.

   View third picture

d) What is the probability that

    View forth picture.

c is the final : )

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
