Answer

Explanation:

Step1: Recall box - plot properties

In a box - plot, the box and whiskers represent different parts of the data distribution. The left - hand side of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), and the right - hand side of the box is the third quartile ($Q_3$). The whiskers extend to the minimum and maximum values. Here, the value of 100 is the first quartile ($Q_1$).

Step2: Use quartile concept for fraction

Quartiles divide the data into four equal parts. The first quartile ($Q_1$) represents the 25th percentile of the data. So, the fraction of data that is 100 or more (i.e., from $Q_1$ to the maximum) is $\frac{3}{4}$ since $1 - \frac{1}{4}=\frac{3}{4}$.

Answer:

$\frac{3}{4}$
