Answer: The required probability is 0.004.

Step-by-step explanation:

Since we have given that

Number of pieces = 50

Number of defective pieces = 5

So, we need to draw 2 defective pieces.

So, the probability of drawing 2 defective pieces one after the other on the first and second samples would be

\dfrac{5}{50}\times \dfrac{4}{49}\\\\=\dfrac{20}{2450}\\\\=0.004

Hence, the required probability is 0.004.

Alex Ar [27]

Answer:

The insurance company can make $0.78 for each policy that it sells

Step-by-step explanation:

The loss incurred to the insurance company for each death claim is:

L = \$1-\$100,000=-\$99,999

This event has a 22 in 10 million probability of happening.

The gain for the company for each policy not claimed is:

G= \$1

This event has a 9,999,978 in 10 million probability of happening.

The expected value is:

EV =\$1*\frac{9,999,978}{10,000,000} -\$99,999*\frac{22}{10,000,000} \\EV=\$0.78

Therefore, over the long run, the insurance company can make $0.78 for each policy that it sells.
