Answer :
That’s it, the probability of getting tail on a single coin toss times the number of observations.
In this case, 1/2 * 72 = 36
However, there’s something called chance error. How much do you expect the result to differ from the expected value? It can be calculated as follows:
The Standard Deviation of this experiment is √(0.5)(0.5) =0.5
The Standard Error is √72 (0.5) ≈ 4.18330 round to the nearst tenth is 4
So, the expected value is 36, give or take 4.
And since the number of tails in a toss coin experiment is normally distributed, then you can expect the number of tails to be between -2 and +2 SEs from the expected value 95% of the time.
In other words, if you repeat this experiment a large number of times, you can expect to obtain between 27 and 43 tails 95% of the time.

Answer:
X×W
Step-by-step explanation:
Product multiplies, whereas addition increases value steadily. Subtraction reduces a value, hence X×W has the greatest value.

Hey there! I'm happy to help!
If the model airplanes flies 22 feet in 2 seconds, it travels 11 feet in 1 second.
There are 60 seconds in one minute. We multiply 11 by 60, giving 660 feet in 1 minute.
There are 60 minutes in one hour. We multiply 660 by 60, giving us 39600 feet in 1 hour.
There are 5280 feet in a mile. To find our speed in mph, we divide 39600 by 5280, giving us 7.5 mph.
Have a wonderful day! :D
