Ch.4 Assignment 2 Student's Last Name Similar problems and their solutions you can find in the Lectures, Class - and Write the step-by-step solution and explanations. Home Works. I will not give full credit for incomplete work. Express the indicated degree of likelihood as a probability value. 4 pt. 1. You have a 50-50 chance of choosing the correct answer" A)0.9 B)0.50 C)0.25 D) 50 Which of the following cannot be a probability? 4 pt. 2. A) B) C) 3. Find the indicated probability 4 pt. The probability that Luis will pass his statistics test is 0.65. Find the probability that he will fail his statistics test. Find the indicated probability 10 In a poll, respondents were asked whether they had ever been in a car accident. 471 respondents indicated that they had been in a car accident and 420 respondents said that they had not been in a car accident. If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident?Explanation / Answer
1) the answer is "B"(0.50) the probablity chance is 1/2=0.50
2) the answer is "A" (5/3) reason is not gain to 5 outcomes in 3
3)the luis will pass his statistic probability is 0.65 so his exam failing probablity is 1-0.65=0.35
So the failing in his statistic Probability is 0.35
4)p(accident)=471/(471+420)=471/891=0.5287
