Question:

What is the probability of rolling two dice and getting at least one odd number?

Inactive
Alice R.

Given that there are 4 possible outcomes when you roll 2 dice (even + even, even + odd, odd + even, and odd + odd), that 3 of these outcomes include one odd number, and that there is a 1/4 chance of rolling each combination, the overall probability is equal to 3*1/4 = 3/4 or 75%.

The variable must 1) be correlated with the dependent variable and 2) be correlated with at least one of the independent variables in the model.

Question:

Explain the difference between a shift in the demand curve and movement along the demand curve.

Inactive

Movement along the demand curve happens only when there is a change in price, whereas a shift in demand is the result of a change in demand even though the price is still the same as it was before.
