Question

The expected number of head in 100 tosses of an unbiased coin is i want explanation pls​

Answer 1

Hey mate ☺

The expected number of head in 100 tosses of an unbiased coin is

$50$

As Probability of coming head and tail in each toss is 0.5 or

$\frac{1}{2}$

So, 0.5 of 100 tosses is

$100 \times 0.5 = 50$

Hope it helps you ☺✌✌

Answer 2

Step-by-step explanation:

Expected number of heads in case of one toss is head = 0.5 and tail = 0.5

there equal chances of occurrence for heads and tales.

so in case if 100 tosses heads have expectancy of 100×1/2 = 50

and tails also have the same.
