Question

Gene is tossing a normal quarter. He tosses the quarter 12 times and it lands on heads 9 times. If Gene tosses the quarter again, what is the probability that it lands on tails? Input your answer in fraction form.

Answer 1

Answer:

1/2

Step-by-step explanation:

This is an independent event.  It does not matter what happened before the chances of getting a tail on one toss will always be what I want/all outcomes.  There are only 2 outcomes:  heads or tails.  I am only looking for one of those outcomes, so 1/2.
