Answer: 0.48
Explanation:
P(A/B) = P(AnB)/P(B) where:
P(A/B) = The probability of event A occurring given that B has occurred.
P(AnB) = The probability of both events A and B occurring.
P(B) = the probability that event B occurs.
So let
P(A) = Probability that the residents of a household own 2 cars.
P(B) = Probability that the annual household income is greater than $25,000.
The question tells us that
P(A/B) = 0.8
Note that: P(A) = 0.7, P(B) = 0.6.
Since we want to work out P(AnB), because it gives the probability that residents have an annual household income over $25,000 and own 2 cars.
We would Rearrange our initial equation to make P(AnB) the subject formula becoming;
P(A/B) = P(AnB)/P(B)
P(B)*P(A/B) = P(AnB)
So, inserting our probabilities into this equation gives:
0.6*0.8 = 0.48

Explanation:
Game theory looks at the interactions between participants in a competitive game and calculates the best choice for the player.
Dominant strategy is the best option for a player regardless of what the other player is playing
firm a can either earn20 or 70 if it advertises or 5 or 50 if it does not advertise. this is the same for firm B.
Thus the option that would yield the highest payoff is for both firms to advertise.
this is an example of prisoners dilemma
