What is the second step to calculate the probability of an event?

• Identify an event with one result
• Identify the number of favorable outcomes
• Identify the total number of results or outcomes and favorable outcomes that can occur
• Divide the number of favorable outcomes by the total number of possible outcomes

What is the third step to calculate the probability of an event?

• Identify the total number of results or outcomes and favorable outcomes that can occur
• Divide the number of favorable outcomes by the total number of possible outcomes
• Identify the number of favorable outcomes
• Identify an event with one result

What is the difference between total number of outcomes and favorable outcomes?

• Total number of outcomes is the number of outcomes, while favorable outcomes are the number of events
• Total number of outcomes is the number of events, while favorable outcomes are the number of outcomes
• Total number of outcomes is the desired outcomes, while favorable outcomes are all possible outcomes
• Total number of outcomes is all possible outcomes, while favorable outcomes are the desired outcomes

What is the formula to calculate probability?

• Multiply the number of favorable outcomes by the total number of possible outcomes
• Divide the number of favorable outcomes by the total number of possible outcomes
• Subtract the number of favorable outcomes from the total number of possible outcomes
• Add the number of favorable outcomes to the total number of possible outcomes
