1. A gambler in Las Vegas is cutting a deck of cards for $1‚000. What is the probability that the card for the gambler will be the following? a. A face card – there are 12 face cards in a deck of 52 cards. The probability would be 12/52 b. A queen – there are 4 queens in a deck‚ so the probability would be 4/52 c. A Spade - There are 13 cards of each suit so the probability is 13/52 or ¼. d. A jack of spades - There is only 1 jack of spades in a deck‚ so the probability would be 1/52

BA 117 Problem Set #1 - CVP Deadline: November 26‚ 2011 A. The break-even point in units can be computed as Fixed Costs divided by the contribution margin per unit. On the other hand‚ the break-even point in pesos can be computed as Fixed Costs divided by the contribution margin ratio. Using the profit equation π = TR – TC; where π = operating profit‚ TR = Total Revenue and TC = Total Cost‚ derive the break-even formulas. B. From the profit equation π = TR – TC‚ derive the formula for the
