The refractive index of a material is a dimensionless number that describes how fast light travels through the material. It is defined as n={\frac {c}{v}}, where c is the speed of light in vacuum and v is the phase velocity of light in the medium.
the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

given,
86 out of every 100 TV households have at least one remote control
Probability of any material is calculated by.
now, Calculating probability that at least one remote control
q = 1 - 0.86
q = 0.14
