The table shows the results when a student tossed a die many times.Use the information to answer the question belowHow many times did the student throw the die?
Concept:The frequency of each number tells how many times it came up. Every throw gives exactly one number, so the total number of throws is the sum of all the frequencies.Given:Frequencies for 1 to 6: 4,3,3,2,3,5Solution:Total throws =4+3+3+2+3+5Group the numbers: (4+3+3)+(2+3+5)=10+10=20Key point: Do not add the die numbers 1+2+⋯+6=21 (option C) or count the faces (6, option A); add the frequencies.Answer:Option D (20)
