Tony Horton · Answer 1

probability of there meeting = 15 / (60-15) = 15/45 = 0.333 = 33%

Step-by-step explanation:

favorable event = + - 15 minutes

total time they can eat launch is between noon and 1pm = 60minutes

they are both known for non punctuality, that means they cant meet up at 12noon, let assume 15minutes pass noon.

probability of there meeting = 15 / (60-15) = 15/45 = 0.333 = 33%

which is probably saying they will not meet for lunch that day.
