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

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
