Construct the discrete probability distribution for the random variable described. Express the probabilities as simplified fractions.
The number of heads in 5 tosses of a coin. Please answer in a table to understand better.
Answer :-
Given ,
By using this formula we can solve this sum .
Where ,
n =Number of heads = 5
x = possibilities of number of heads = 0,1,2,3,4,5
p = probability of head
p = possibility of getting heads of a coin / total number of faces of a coin
q = probability of tail
q = 1 - p
q = 1 -0.5
q = 0.5
