The numbers less than 4 are 1, 2, and 3. From the table, a 1 was rolled 6 times, a 2 was rolled 4 times, and a 3 was rolled 8 times. Therefore, a number less than 4 was rolled 6+4+8=18 times ​ It is given that the number cube was rolled 50 times. ​ The relative frequency of rolling a number less than 4 is: ​ а(аrequency of rolling a number less than 4 total number of rolls)×100 ​ Since a number less than 4 was rolled 18 times and the total number of rolls is 50, then the relative frequency of rolling a number less than 4 is: ​ 1850×100%=18×10050%=18×2%=36%
