Let's break down the problem step by step: ### **Step 1: Understand the Problem** You are asked to determine the odds **against** a person having A+ blood, using the percentages shown in the circle graph. ### **Step 2: Get the Data from the Graph** From the graph, the percentages for each blood type are: - **AB+**: 1% - **AB-**: 1% - **B+**: 7% - **B-**: 2% - **A-**: 6% - **A+**: 34% - **O-**: 6% - **O+**: 39% ### **Step 3: Find the Probability of Having A+ Blood** - The probability that a randomly selected person has **A+** blood = **34%** or **34 out of 100**. ### **Step 4: Find the Probability of NOT Having A+ Blood** - The probability that a person does **not** have A+ blood = \( 100\% - 34\% = 66\% \), or **66 out of 100**. ### **Step 5: Write the Odds Against Having A+ Blood** - **Odds against** = (Number of people **not** having A+) : (Number of people **having** A+) - So, odds against A+ = **66 : 34** ### **Step 6: Simplify the Odds** - Divide both numbers by 2: \( \frac{66}{2} : \frac{34}{2} = 33 : 17 \) ### **Final Answer** > The odds **against** a person having A+ blood are **33 : 17**.
