Question

there are 100 balloons in a box, of which 40 are blue. what is the probability of randomly picking a blue balloon from the box?

Explanation:

Step1: Determine the formula for probability

The formula for probability is \( P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \).

Step2: Identify the values

Here, the number of favorable outcomes (blue balloons) is \( 40 \), and the total number of outcomes (total balloons) is \( 100 \).

Step3: Calculate the probability

Substitute the values into the formula: \( P=\frac{40}{100} = 0.4\).

Step4: Convert to percentage

Multiply by \( 100\) to get the percentage: \( 0.4\times100\% = 40\%\).

Answer:

\(40\%\) (the option with \(40\%\) text)
