Problem Analysis

In this problem, we are given a bag containing 50 balls, with 27 red balls, 4 green balls, 17 black balls, and an equal number of white and blue balls. We need to find the probability of Anuta randomly selecting either a red or a white ball from the bag.

Solution

To find the probability, we need to determine the total number of favorable outcomes (red or white balls) and the total number of possible outcomes (all balls in the bag).

The total number of favorable outcomes is the sum of the number of red balls and the number of white balls. Since the number of white balls is equal to the number of blue balls, we can consider them together as one category.

The total number of possible outcomes is the total number of balls in the bag.

Let's calculate the probability step by step:

Step 1: Calculate the total number of favorable outcomes: - Number of red balls: 27 - Number of white balls: (total number of balls - number of red balls - number of green balls - number of black balls) / 2 = (50 - 27 - 4 - 17) / 2 = 2

Total number of favorable outcomes = Number of red balls + Number of white balls = 27 + 2 = 29

Step 2: Calculate the total number of possible outcomes: - Total number of balls in the bag: 50

Step 3: Calculate the probability: - Probability = Total number of favorable outcomes / Total number of possible outcomes = 29 / 50 = 0.58

Therefore, the probability of Anuta randomly selecting either a red or a white ball from the bag is 0.58.
