Answer: The required probability is [tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
Since we have given that
Number of people came into Brad's store = 48
Number of them made a purchase = 40
So, the experimental probability that the next person to come into the store will make a purchase would be
[tex]\dfrac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\dfrac{40}{48}\\\\=\dfrac{5}{6}[/tex]
Hence, the required probability is [tex]\dfrac{5}{6}[/tex]
