Probability Exercise A bowl contains n black balls (n ∈ N *) and two oval balls. We draw two balls in a row from this bowl without repeating before the next drawing. 1. What is the probability of drawing two white balls? 2. We denote by U n the probability of drawing two balls of the same color. a) Express U n in terms of n. b) Calculate: * Interpret the result. The solution 1. Calculate the probability of drawing two white balls. We call event A: “drawing two white balls . ” and from it: P(A) is the number of appropriate cases for the event A division The number of possible cases for this experiment. 2. Calculate the probability of drawing two balls of the same color. We call event B: “Two balls of the same color are drawn.” We call the event N: “drawing two black balls.” We have: P(B)= P(A)+P(N) So: So: b) Calculate: * Interpretation of the result. This result is interpreted as when the n
