Question

For the Experiment, flip a coin until heads shows, assume that the probability of heads on one flip is 3/5 we define a RV (random variable) X= the number of flip. 1)what are the possible values of X. Find the probability distribution function for X: gives the first four values, and then find a general formula for the probability that x=n.

Answer 1

you could get it on the first try, the second try, the third try etc
\[X=1,2,3,...\]

Answer 2

p(x=1)= 3/5
p(x=2)= 2/5*3/5
p(x=3)= (2/5)^2* 3/5
?

Answer 3

@satellite73 that all i need to do ?
