All right.
00:02
So the question here says that there is an insurer who offers auto insurance, so fire insurance and flood insurance.
00:08
And it offers only these policies.
00:10
So the company offers flood insurance only to fire insurance policy holders, right? that is policyholders with fire insurance can add flood insurance, right? so 80 % of all policyholders have auto insurance, right? so the probability for auto insurance is 0 .8.
00:31
So 80 % of all policy holders have auto insurance.
00:35
40 % have fire insurance, right? so they have fire insurance is 40%.
00:44
And 25 % of policy holders with auto insurance also have fire insurance, right? so here, okay, so the fire insurance, they also have.
01:01
Insurance right okay so we'll use here if for fire right alright so fire insurance is 0 .5 this is 0 .25 okay now 50 % of policyholders with fire insurance also have flood insurance so the probability of having flood insurance given they have fire insurance is 0 .5 then 50 % of policyholders with flood insurance also have auto insurance.
01:40
So the probability of having auto insurance given they have flood insurance is 0 .5.
01:47
Now in this case we have, it says that of the policyholders that have fire insurance determine the fraction that have neither auto insurance nor flood insurance...
