Question

Suppose that the experiment to toss a balanced coin three times independently. Define the following events
• A is the event of getting at least one head
• B is the event of getting exactly two heads and one tail
• C is the event of getting all three coins with the same side

Please answer I have exam tomorrow and I don’t know how I answer

Answer 1

Answer:

Probability = 7/9

Probability = 3/9

Probability = 2/9

Explanation:

Total probability = 2³ = 9

Computation:

A is the event of getting at least one head

Probability = Event of getting at least one head / Total event

Probability = 7/9

B is the event of getting exactly two heads and one tail

Probability = 3/9

C is the event of getting all three coins with the same side

Probability = 2/9
