Math Grade 7 Quiz Understanding Probability Through Relative Frequency – 7.SP.C.6
This topic delves into the concept of approximating the probability of an event by observing the long-term relative frequency through data collection. It allows students to predict relative frequency when given a probability and vice versa. An essential aspect to remember is that while these approximations can be very close, exact matches are rare due to the inherent nature of chance.
