Six coins are tossed 6,400 times. Using Poisson distribution, find the
approximate probability of getting six heads two times.

Let the coin be unbaised coin

Therefore the probability of getting 6 heads with six coins = (1/2)^6 = 1/64 = p (say)

Then np = 6400 * 1/64 = 100=m (say)

Then according to poissons law

P(X=x) =

=
