Probability =![\frac{g}{g+o} + \frac{g-1}{g+o}](/tpl/images/0551/1890/6c138.png)
Step-by-step explanation:
Let g represent the number of green beads , and o represent the number of orange beads.
due to the fact that Ann is selecting the bead without replacing i randomly
the probability (Pr) of Ann selecting a green bead and then an orange one =![\frac{g}{g+o} +\frac{g-1}{g+o}](/tpl/images/0551/1890/bd223.png)
