Question

if a coin was flipped 30 times, how many times would it land on tails?

Answer 1

It is expected that it would land on tails 15 times

Here, we want to get the number of times the coin will land on it tail

Mathematically, the probability that a coin will land on its head or on its tail is the same at 1/2

So the number of times out of 30 flips will be;

$\frac{1}{2}\times30\text{ = 15 times}$
