A fair coin is tossed three times. Let X be the number of heads in thetosses minus the number of tails. Find the probability distribution of X.

P(3) = 1/8

P(1) = 3/8

P(-1) = 3/8

P(-3) = 1/8

Step-by-step explanation:

Given that :

Coin is tossed 3 times :

Kindly check attached picture for detailed explanation

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840
