280,000 would be the correct amount
Answer:
Step-by-step explanation:
Answer:
0.4
Step-by-step explanation:
Given that:
P(debt) = P(D) = Probability of being in debt = 0.7
P(debt n Midwest) = P(Dn M) = probability of being in debt and lives in Midwest = 0.280
The probability that a randomly selected farmer lives in the Midwest given that he is in debt is?
P(M | D) = p(D n M) / p(D)
P(M | D) = 0.280 / 0.7
P(M | D) = 0.4
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2
Hope this helps :)
The expectation value is simply obtained by multiplying the probability of each outcome by each possible value. These are then summed for each outcome to obtain the expectation value. In the board game, if there is a 60% chance that you will move 4 spaces forward (+4) and a 40% chance that you will move back 2 spaces then expected value for number of spaces is (0.6 x 4) + (0.4 x -2) = 2.4 - 0.8 = 1.6 spaces.
