An insurance company offers four different de- ductible levels none, low, medium, and high for its homeowner s policyholders and three different levels low, medium, and high for its automobile policyholders. The accompanying table gives pro- portions for the various categories of policyholders who have both types of insurance. For example, the proportion of individuals with both low home- owner s deductible and low auto deductible is .06 (6% of all such individuals).
