An eighth-grade class rolls a number cube with faces labeled 1 through 6.
The results of 50 rolls are recorded in the table below.
Find the relative frequency that a number less than 4 is rolled.
\(\begin{array}{|c|c|}\hline \text{Outcome} & 11 & 22 & 33 & 44 & 55 & 66 \\ \hline \text{Frequency} & 66 & 44 & 88 & 1212 & 1010 & 1010 \\ \hline \end{array}\)
A number less than 4 was rolled \(\times ?\).
The number cube was rolled \(\times ?\).
The relative frequency of rolling a number less than 4 is \(?\%\).
a. \(4u-3v-w=0\)
b. \(4 \times 324 \times 32\)
c. \(4×(16×25)4×(16×25)\)
d. \((250+86)+50\)
