Answer:
almost 0%
Step-by-step explanation:
Given that for an insurance company with 10000 automobile policy holders, the expected yearly claim per policyholder is $240 with a standard deaviation of 800
using normal approximation, the probability that the total yearly claim exceeds $2.7 million is calculated as follows:
Sea sumatoria de x = SUMX, tenemos que:
![P (SUMX \geq 2700000) = P(\frac{SUMX - 240*10000}{800 *\sqrt{10000} } \geq \frac{2700000 - 240*10000}{800 *\sqrt{10000} })](https://tex.z-dn.net/?f=P%20%28SUMX%20%5Cgeq%202700000%29%20%3D%20P%28%5Cfrac%7BSUMX%20-%20240%2A10000%7D%7B800%20%2A%5Csqrt%7B10000%7D%20%7D%20%5Cgeq%20%5Cfrac%7B2700000%20-%20240%2A10000%7D%7B800%20%2A%5Csqrt%7B10000%7D%20%7D%29)
![= P (z\geq \frac{2700000 - 240*10000}{800 *\sqrt{10000}})](https://tex.z-dn.net/?f=%3D%20P%20%28z%5Cgeq%20%5Cfrac%7B2700000%20-%20240%2A10000%7D%7B800%20%2A%5Csqrt%7B10000%7D%7D%29)
= P (z => 3.75)
= 1 - P ( z < 3.75)
P = 1 - 0.999912
P = 0.000088
Which means that the probability is almost 0%

Remember to look at words that indicate an operation is to take place (Eg: "times" (x) "less than" (-) "Twice x" (2x))

73+42 is correct because it’s addition
