I got it right on edge :)

Answer 2

a. Sunday

Step-by-step explanation:

Probability ranges from 0-1. 0 being the least chance and one being completely sure.

The probability of receiving a tip of at least 15% for the different days is as follows

Monday : 82/126 = 0.65

Tuesday: 87/106= 0.82

Wednesday: 93/103= 0.90

Thursday : 68/126 = 0.54

Friday :91/153= 0.59

Saturday: 83/156 = 0.53

Sunday: 64/137= 0.46

The day with the lowest probability is Sunday.
