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 longterm 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.
