Answer:
(a) The probability that each of them win five games is 0.2461.
(b) The probability that the computer wins seven games is 0.1172.
(c) The probability that the human wins at least 7 games is 0.1711.
Step-by-step explanation:
Let the random variable <em>X</em> = the human wins a chess game.
The probability that the human wins a game is, P (X) = <em>p</em> = 0.50.
The number of games played by the computer and the human is, <em>n </em>= 10.
The random variable
The probability distribution of the Binomial random variable <em>X</em> is:
(a)
If both the computer and the human wins five games each then the probability of the human winning 5 games is:
Thus, the probability that each of them win five games is 0.2461.
(b)
If the computer wins 7 games then the number of games won by the human is, 10 - 7 = 3.
P (Computer winning 7 games) = P (Human winning 3 games)
The probability that the human wins 3 games is:
Thus, the probability that the computer wins seven games is 0.1172.
(c)
Compute the probability that the human wins at least 7 games as follows:
Thus, the probability that the human wins at least 7 games is 0.1711.
