# Complement the formula for the coil

Linear attenuation coefficient | Radiology Reference ...- Complement the formula for the coil ,Linear attenuation coefficient (µ) is a constant that describes the fraction of attenuated incident photons in a monoenergetic beam per unit thickness of a material 1.It includes all possible interactions including coherent scatter, Compton scatter and photoelectric effect 1.. Its complement is the transmitted portion of the beam. It is expressed numerically in units of cm-1.BASIC PROBABILITYThe formula for combinations is . n = Total objects to arrange . r = Number of objects taken from the total to be used in the arrangements. The symbol for number of combinations is often shown as . When the symbol appears in a formula, the number of combinations is to be computed using the combination formula. Example 7
