In a certain computer game, the computer can make 1 of 4 moves, which it chooses randomly. according to the game manual, the probability it will make 1 of the moves is 0.5, the probability it will make 2 of the remaining moves is 0.25, and the probability it will make the last move is unknown, but nonzero. why can the player immediately know that these probabilities are incorrect?

Because probability is based on 1, and the sum of the three situations is already 1.

Step-by-step explanation:

When you are calculating the probability of something happening you have a finite number of possibilities, and the sum of those would be always 1 when you are doing a precentage possibility, in this example you have 50% chance of a movement happening, 25% of each of the other two, that adds up to a 100% of the chances you have to get something, which aint possible.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

2x + 8
