If you deal 3 cards out of a full deck what is the probability that exactly one card would be a spade?
The probability of getting a spade out of a full deck is 13/52 = 1/4. Now, to get exactly one spade you have the following possibilities: a. Spade first, then others: 13/52*39/51*38/50 b. Other, then Spade, then other: 39/52*13/51*38/50 c. Other, then other, then spade: 39/52*38/51*13/50. Sum them up, and you get 3*13*39*38/(52*51*50) = 0.4385 To understand this best, please draw a tree.

Of 50 students surveyed only 6 percent said they would cheat on a test if they had a chance. How many students would cheat if they had a chance?
The fact that 6% said they would cheat if they had a chance does not mean that 6% would actually cheat. Even if I were determined to cheat, I would not admit my intention in a survey.
