Final answer:
An individual will forget 50% of memorized information in 20 minutes and 70% in 24 hours, according to the Ebbinghaus forgetting curve.
Step-by-step explanation:
If you do not work with the material you have learned within 20 minutes to 24 hours of receiving it, you will forget a significant percentage of it. Based on the research by German psychologist Hermann Ebbinghaus, an average person will lose 50% of the memorized information after 20 minutes and 70% of the information after 24 hours. This phenomenon is described by the Ebbinghaus forgetting curve, which illustrates the decline of memory retention over time
