    Did you try to use a uniform distribution for this problem?

    i tried this, \[f(x)=\frac{ 1 }{ (0.2161-0.2035 )}\] \[f(x)=\frac{ 5000 }{ 63 }\] but i don't know the limits for the integral and i'm not sure if this is correct

    the limit is from .2125 to the end of the domain .2161

    \[\int\limits_{0.2125}^{0.2161}\frac{ 5000 }{ 63 }\] the answer is 0.2857
