Complete Question:
Suppose George wins 34% of all chess games.
(a) What is the probability that George wins two chess games in a row?
(b) What is the probability that George wins three chess games in a row?
(c) When events are independent, their complements are independent as well. Use this result to determine the probability that George wins three chess games in a row, but does not win four in a row.
(a)![Probability = 0.1156](/tpl/images/0863/3045/570bf.png)
(b)![Probability = 0.0393](/tpl/images/0863/3045/fd95b.png)
(c)![Probability = 0.0259](/tpl/images/0863/3045/3e735.png)
Step-by-step explanation:
Represent Win with W
So, we have:
Solving (a): Winning two in a row;
This is represented by WW and is calculated as thus:
Solving (b): Winning three in a row;
This is represented by WWW and is calculated as thus:
Solving (c): Wins three in a row but lost the fourth
Represent Losing with L
L is calculated as:
This probability is represented by WWWL and is calculated as thus:
