Question

A fair coin is tossed 20 times. Find the probabilitythat the number of heads occurring is between 10 and 14 inclusiveby using the normal approximation to the binomialdistribution. Can poisson distribution approximate hypergeometricdistribution. Please donot send fake answer A fair coin is tossed 20 times.

Explanation / Answer

Since it is a fair coin then the probability ofgetting a head = probability of getting a tail = 0.5 then mean = = np = 20*0.5 =10 and standard deviation = =np(1-p) =20*0.5*0.5 = 2.236 Then we have
