Answer:
0.3
Step-by-step explanation:
Total number of cases = 60.
favourable number of cases = 18. (Since 18 of them are wearing green shirt)
As we know probability of an event is given by ,
P = Favourable number of cases divided by Total number of cases
Thus here,
P = [tex]\frac{18}{60}[/tex]
= [tex]\frac{3}{10}[/tex] or 0.3
