Webb15 nov. 2024 · The Law of Large Numbers concerns the sample average, whereby as the sample size increases, the sample average converges towards the expected value. So in your case you would sample from the distribution and take the mean. Webb9.3 The Strong Law of Large Numbers Theorem 62 Let (Xn)n≥1be a sequence of independent and identically distributed (iid) random variables with E(X4 1) < ∞ and E(X1) = µ. Then Sn n := 1 n Xn i=1 Xi→ µ almost surely. Fact 63 Theorem 62 remains valid without the assumption E(X4 1) < ∞, just assuming E( X1 ) < ∞.

Webbinsurance company is able to bear the same risk in large numbers. Here apply what is called the law of large number. The law of large numbers states that if the amount of exposure to losses increases, then the predicted loss will be closer to the actual loss. The use of the law of large numbers allows the number of losses to be predicted better. 1.
