Two life insurance policies, each with a death benefit of 10,000 and a one-time premium of 500, are sold to a couple, one for ea
Kazeer [188]

Answer:896.9

Step-by-step explanation:

Let x denotes excess premium over claims

E\left ( x|husband survives\right ), 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

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

kaheart [24]

6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Step-by-step explanation:

We need to find how much flour is needed for 9 cups of oatmeal.

Solving by using Unitary Method

3 cups of oatmeal require flour = 2 cups

1 cup of oatmeal require flour = \frac{2}{3}

9 cups of oatmeal require flour = \frac{2}{3}*9\\

                                                   = 6

So,  6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal
