Question 44521
Toss three coins 20 times and determine the empirical probability of obtaining three heads. Using the data from part a, determine the empirical probability of not obtaining 3 heads and determine the empirical probability of obtaining two heads and a tail.
HOPE YOU WANT MATHEMATICAL CALCULATION..NOT BY EXPERIMENT
PROBABILITY OF HEAD ON ONE COIN =1/2=0.5.
P OF ALL 3 HEADS=(1/2)^3=1/8
P NOT OBTAINING 3 HEADS =1-1/8=7/8
P OF TAIL ON ONE COIN=1/2
P OF 2 HEADS AND ONE TAIL=(1/2)^3=1/8
