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
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 
is an irrational number ⇒ answer B
Step-by-step explanation:
Let us explain the meaning of:
- A rational number is a number that can be written as a fraction
- An irrational number is a number that cannot be expressed as a fraction
Examples:
Rational numbers : 10 , 
, 0.333
Irrational numbers : π , √8 , ∛25 , (2 + √5) , 
∵ 
∵ 3 is a rational number
∴ 
is a rational number
∵
∵ There is no square root of 8
∴ is an irrational number
∵ 0.3333 can be expressed as 
∴ 0.3333 is a rational number
∵ 
is a fraction
∵ All fractions are rational numbers
∴ is a rational number
is an irrational number
