Make a relative frequency table and make the histogram by measuring $6$ equal widths. The relative frequency column is the percent frequency, or probability. Draw vertical bars to the height of the corresponding relative frequencies.

Value Frequency Relative frequency
30 3 $\frac{3}{18}=0.167$ or $16.7\%$
40 4 $\frac{4}{18}=0.222$ or $22.2\%$
50 0 $\frac{0}{18}=0$ or $0\%$
60 4 $\frac{4}{18}=0.222$ or $22.2\%$
70 3 $\frac{3}{18}=0.167$ or $16.7\%$
80 3 $\frac{3}{18}=0.167$ or $16.7\%$
90 0 $\frac{0}{18}=0$ or $0\%$
100 1 $\frac{1}{18}=0.056$ or $5.6\%$
Total 18 $\frac{18}{18}=1.00$ or $100\%$
