why on earth are you adding them up

ummmmm .... because math?

There are 32 possible H/T outcomes in tossing 5 coins. Of those 32 possible outcomes 5 of them contain exactly 1 head. Each of those has a probability of 3.125%. 5*3.125% = 15.6% (rounded)

You gotta be trolling me because nobody can be this stupid. Hell my 4 yo granddaughter knows how to count.

#sigh

But to calculate exactly one heads is this

1/2*(1/2)^4*5=1.5625

NNNNN

I am not looking at the results

The interest is that by offering choice it changes the probabilities ,

It changes the nature of the problem and the way probabilities are calculated; it is now treated as conditional probability.

Seriously, if you want to actually understand what you are doing, you need to learn basic probability theory.

What do you suppose multiplication is? Consider

Your equation is poorly formulated; it should be written more like 0.5⁵ x 5 = 0.15625
What you wrote does not reflect the way probabilities are calculated.

Conditional probability ? the probability is a variate there is no conditions, a strict inequality.

This calculation come from scientists and I have checked it several times to be correct on several forums.

Naked scientist one of the forums that confirmed that piece of maths.

This maths is my own.

cov(X,Y) =(σA,σt)=(σ1/52λ)/Z

Based on this
