The answer would be b). -4
Reason being you have to minus four dollars to get to 14. If you chose c, then you would be adding four dollars, which isn't right. So your answer is b.
The sixth choice is the correct answer
Answer:
The probability of getting at least one hit in 5 games is 0.772
Step-by-step explanation:
The correct question is as follows;
One interpretation of a baseball player's batting average is as the empirical probability of gettig a hit each time the player goes to bat. If a player witt a batting average of 0.256 bats 5 times in a game, and each at-bat is an independent event, what is the probability of the player getting at least one hit in the game?
We proceed with the answer as follows;
Here, we want to calculate the probability of a player with a certain batting average getting at least one hit in a game if he bats 5 times
Mathematically, Probability of getting at least one hit in 5 games = 1 - Probability of getting no hit in 5 games
Let p = probability of getting hit in a game = 0.256
q = Probability of getting no hit in a game = 1-0.256 = 0.744
So the probability of getting no hits in 5 games will be 0.744^5 = 0.228
Thus, the probability of getting at least one hit in the 5 games = 1 - 0.228 = 0.772
