2:Laticia randomly selected 25% of the seventh-grade students in her school and asked them their favorite season. Of the students surveyed, 51 chose summer as their favorite season. Based on the data, what is the most reasonable prediction of the nu?

Assuming that there is an equal chance of each season being chosen as favourite then to get the total number of students you would multiply 51 by four (four seasons) to predict how many students were surveyed and then multiply by four again (only 25% were surveyed). That leaves you with 204
