Drinks are prepared and arranged on a table for a party. The probability that a drink is grape juice is 0.3. The probability that a drink has a straw is 0.3. The probability that a drink is grape juice and has a straw is 0.1. Use the addition rule to determine the probability that a drink is grape juice or has a straw. Enter your answer as a decimal, rounded to the nearest tenth, like this: 0.4

0.5

Step-by-step explanation:

P(grape or straw) = P(grape) + P(straw) − P(grape and straw)

P(grape or straw) = 0.3 + 0.3 − 0.1

P(grape or straw) = 0.5
