In coin tossing type gambling where the casino uses a loaded coin with p slightly larger than q, the location of the random walker at time t = n represents the expected profit of the casino after its customers play n games, and σ represents the likely fluctuations about this statistical average (e. g., over many days). the profits grow linear in n and the fluctuations grow only as σ ∼ √ 1/ n.

d is the answer i came up with

c, 1a hope this

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
