Tossing a coin is a binomial experiment.
Now lets say there are 'n' repeated trials to get heads. Each of the trials can result in either a head or a tail.
All of these trials are independent since the result of one trial does not affect the result of the next trial.
Now, for 'n' repeated trials the total number of successes is given by

where 'r' denotes the number of successful results.
In our case
and
,
Substituting the values we get,


Therefore, there are 1352078 ways to get heads if a person tosses a coin 23 times.
Answer: 30
Step-by-step explanation:
The rate would be
22000 gallons per 16 hours or
rate = 22000/16 = 1375 gallons/hr
Can't see it the equation is to blurry.
Correct me if I’m wrong, I believe you have to add all of those numbers together. Then divide after and plug in those remaining digits
