Question
..o.lashia if it is not probabili probability values must be rounded to three decimal t specified in the question. If it is possible, show your work in order to receive credit for it. 1. (6pts) a) If A denotes some event, what does A denote? dsnas.at sud b) If P(A) 0.003, what is the value of P(A)? P(A ) = c) If P(A) = 0.003, is A unusual? No Yes 2. (8pts) Which of the following values cannot be probabilities? o, 2, 3/7, 5/3, -0.45, 0.03, 1, 3.26, v2 Circle all the values that cannot be probabilities. 3. (5 pts) In a certain instant lottery game, the chances of a win are stated as 5 in 18." Express the indicated degree of likelihood as a probability value between 0 and 1 inclusive. 0 l sExplanation / Answer
1 a) consists of all events that do not appear in A, it is called complement of A.
b) P(A) = 0.003 ; P() = 1 - P(A) = 1- 0.003 = 0.997
c) Outcomes less than 0.05 are unusual, So, the answer is NO
2) There are no negative probabilities , limits of probabilities are 0 and 1
-0.45, 3.26, 2
3) Let W be the degree of likelihood of winning
So, P(W) = 5 / 18 = 0.2778
