not black

The correct Answer is:
To find the probability that a ball drawn from the jar is not black, we can follow these steps: ### Step 1: Count the total number of balls in the jar. - We have: - Blue balls: 3 - Black balls: 2 - Red balls: 6 - White balls: 8 **Total number of balls = Blue + Black + Red + White** \[ \text{Total} = 3 + 2 + 6 + 8 = 19 \] ### Step 2: Count the number of favorable outcomes (not black balls). - The favorable outcomes are the blue, red, and white balls. - We have: - Blue balls: 3 - Red balls: 6 - White balls: 8 **Total number of favorable outcomes = Blue + Red + White** \[ \text{Favorable outcomes} = 3 + 6 + 8 = 17 \] ### Step 3: Calculate the probability of drawing a ball that is not black. - The probability \( P \) of an event is given by the formula: \[ P(\text{not black}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \] \[ P(\text{not black}) = \frac{17}{19} \] ### Final Answer: The probability that the ball drawn is not black is \( \frac{17}{19} \). ---
