Question

can you please give the equation used and give step by step detail

solve it all the way put please

Answer 1

What is the probability are you trying to find?

 

Here is a table created in MS Excel using the Binomial Distribution.

p = Probability of "Success" = Probability of Head = 4/9

 

 

The binomial distribution is ( 4 choose k) * (4/9)^k * (1-4/9) ^ (4-k)

 

k     N choose k       Probability of k heads       %
0        1                         0.095259869       9.526%
1        4                         0.304831581     30.483%
2        6                         0.365797897     36.580%
3        4                         0.195092212     19.509%
4        1                         0.039018442       3.902%
