Best ResponseYou've already chosen the best response.0if assignment is random, then the probability of something is always (number of success possibilities)/ (total number of possibilities)

Best ResponseYou've already chosen the best response.0so there are a total of six possibilities and we can actually list them all:

Best ResponseYou've already chosen the best response.0ok so let's list the six possibilities anyway and see where that gets us

Best ResponseYou've already chosen the best response.01. 2x + 3 = 5 2. 2x + 5 = 3 3. 3x + 5 = 2 4. 3x + 2 = 5 5. 5x + 3 = 2 6. 5x + 2 = 3

Best ResponseYou've already chosen the best response.0so out of the six possibilities, 3 are positive, 3 are negative

Best ResponseYou've already chosen the best response.0so thats a 50 percent probabilty

Best ResponseYou've already chosen the best response.0and sometimes there's no systematic theorem or rule  it's just #outcomes/#possible outcomes
