Rajani planted an herb garden with an equal number of rosemary, thyme, and sage plants.
Let x be the unknown number of herbs she planted.
rosemary = thyme = sage = x
The total number of herbs is
total = x + x + x = 3x
So, the probability that she selects thyme plants is
[tex]\begin{gathered} P(thyme)=\frac{number\: of\: thyme\: plants}{total\: number\: of\: plants} \\ P(thyme)=\frac{x}{3x} \\ P(thyme)=\frac{1}{3} \end{gathered}[/tex]Therefore, the probability that she selects thyme plants is 1/3
