Percentiles

Argue that in the case of a continuous random variablethe kth percentileis the point such that
P[X < or= pk/100] = k/100
(k/100 here should be in subscript, it’s not p*k/100)

pk/100 would be the kth percentile for X. For example, the 25th percentile for X is the point p25/100.

The solution argues that in the case of a continuous random variable the kth percentile is the point such that P[X < or= pk/100] = k/100
(k/100 here should be in subscript, it’s not p*k/100).
