Question

there are 25 equally sized balls in a box. of these balls, 20 are blue, 4 are red, and 1 is yellow. if one of these balls is selected from the box at random, what is the probability of selecting a red ball?

Explanation:

Step1: Recall the probability formula

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

Step2: Identify the number of favorable and total outcomes

The number of red balls (favorable outcomes) is \(n = 4\). The total number of balls (total outcomes) is \(N=25\).

Step3: Calculate the probability

Substitute the values into the formula: \(P(\text{red})=\frac{4}{25}\).

Answer:

\(\frac{4}{25}\)
