A phone company surveys a sample of current customers to determine if they use their phones most often to text or use the Intern
et. They sort the data by payment plans, as shown below.
Plan A: 27 text, 21 Internet
Plan B: 13 text, 10 Internet
Answer the questions to determine a conditional probability.
How many customers are on payment plan B?
customers
How many of the customers on plan B text?
customers
What is the probability that a randomly selected customer who is on plan B uses the phone most often to text? Give the answer in fraction form.
1 answer:
Answer: payment B: 23 customers
plan B text: 13 customers
fraction form: 13/23
