A particle size analysis on a soil sample yields the following data.

$\backslash$table$[[$Sieve no$.,\frac{3}{8}",4,10,20,60,200,$Pan$],[$Sieve size $($mm$),9\mathrm{.}53,4\mathrm{.}75,2\mathrm{.}0,0\mathrm{.}84,0\mathrm{.}25,0\mathrm{.}074,-],[$Mass retained $($grams$),0,310,580,380,260,680,210]]$

$($a$)$ Plot the particle size distribution curve.

$($b$)$ Determine the amount of coarse$-$grained and fine$-$grained soils in the soil.
