Answer:896.9
Step-by-step explanation:
Let x denotes excess premium over claims
, There are two possibilities
(i)Only husband survives
This can be possible with a possibility of 0.01
Claims=10,000
Premium collected![=2\times 500=1000](https://tex.z-dn.net/?f=%3D2%5Ctimes%20500%3D1000)
Thus x=1000-10,000=-9000
(ii)Both husband and wife survives
This can occur with a probability of 0.96
Here claims will be 0 as both survives
Premium taken=1000
thus x=1000
The probability that the husband survives is the sum of above cases
=0.96+0.01=0.97
Hence the desired conditional Expectation ![E\left ( x|Husband survives\right ) =0.01\times \left ( -9000\right )+0.96\times \left ( 1000\right )=896.9](https://tex.z-dn.net/?f=E%5Cleft%20%28%20x%7CHusband%20survives%5Cright%20%29%20%3D0.01%5Ctimes%20%5Cleft%20%28%20-9000%5Cright%20%29%2B0.96%5Ctimes%20%5Cleft%20%28%201000%5Cright%20%29%3D896.9)
I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.
I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
