Baxter likes to shoot hoops. When he does he gets 3 out of every 5 shots in.
How many shots would he MISS if he has 20 shots?

2 out of 5 missed, therefore in 20 shots he will miss 8 (4 x 2 - because 5 x 4 = 20, so multiply the number of missed shots by 4 as well)

Out of 60 people surveyed, 30 own a car, 25 own a bike, and 12 own both a car and a bike. What is the probability that a randomly chosen person owns only a car?

Step 1: Find the number of people who own only a car

• People who own a car: 30
• Of these, 12 own both a car and a bike
• So, people who own only a car = 30 - 12 = 18

Step 2: Find the probability

• Probability = (Number who own only a car) / (Total surveyed)
• Probability = 18 / 60
• Probability = 0.3

Final Answer

The probability that a randomly chosen person owns only a car is 0.3 or 30%.
