Answer

Explanation:

Step1: Calculate total number of trials

$7 + 8+10=25$

Step2: Calculate experimental - probability of pink beads

The experimental probability $P(\text{pink})$ of choosing a pink bead is $\frac{7}{25}$.

Step3: Predict number of pink beads in the box

Let $x$ be the number of pink beads in the box. We know there are 175 beads in total. Using the proportion $\frac{x}{175}=\frac{7}{25}$. Cross - multiply: $25x = 7\times175$. Then $x=\frac{7\times175}{25}$. $x = 49$

Answer:

49
