Respuesta :
Answer: a) 0.6, b) [tex]\dfrac{4}{15}[/tex]
Step-by-step explanation:
Since we have given that
Total number of people were surveyed = 150
Number of people that like comedies they bought popcorn that day = 90
Number of people that said they do not buy popcorn = 40
So, Probability of getting who like comedies and bought popcorn = [tex]\dfrac{90}{150}=\dfrac{3}{5}=0.6[/tex]
Probability of getting who said they do not buy popcorn = [tex]\dfrac{40}{150}=\dfrac{4}{15}[/tex]
Hence, a) 0.6, b) [tex]\dfrac{4}{15}[/tex]
