According to the Chronicles of Contrived Statistics (March, 2016), the probability that Elon Musk will offer you a free trip into space in the next month is 26%. The probability that scientists from Area 51 will start selling pet aliens next month is 31%. Finally, the probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 11%. What is the probability that both Elon Musk will offer you a free trip into space and scientists from Area 51 will start selling pet aliens in the next month? Answer in decimal form. Round to two decimal places as needed. Your Answer:

An unreliable company produces a large shipment of blenders where 13% have a defective motor, and 25% have a defective electrical cord and 5% have both defects. If you randomly select a blender in this shipment, find the probability that it has... a) only a defective electrical cord. Write your answer as a percent rounded to 1 decimal place. b) a good motor. Write your answer as a percent rounded to 1 decimal place. c) a good motor and a good electrical cord. Write your answer as a percent rounded to 1 decimal place.
During spring, young moose, unfamiliar with roads and traffic, are wandering around at night in a province, causing risk and road accidents. Suppose that the average number of road accidents involving moose was 4.6 per day. The government increased the number of hunting licenses and cleared brush to improve drivers' visibility. On one day after these measures were implemented, there were two road accidents involving moose. a) What would be the chance of two such accidents or fewer, assuming the government's measures were ineffective? b) Do you think the government's measures were effective? State your reasons clearly. a) The chance of two or fewer accidents is. (Round to three decimal places as needed.) b) Were the government's measures effective? O A. Since the probability of two or fewer accidents is relatively large, it appears that the government's measures were ineffective. O B. While the probability of two or fewer accidents is relatively small, it would not be particularly…
It is suspected that 25% of children may have an adverse reaction to the new RTS,S/AS01 (RTS,S) vaccine that was recommended in October this year by the World Health Organization for the prevention of P. falciparum malaria in children living in the sub-Saharan Africa, where transmission is moderate to high. Suppose the Health Science Faculty of UP is going to test the vaccine on 60 patients. Let: X = the number of children who experienced an adverse reaction. X sample proportion of children who experienced adverse reaction. 60 The distribution of X is with an expected value of and a standard deviation of Round your answer to 4 decimal places. . b) The sampling distribution of p is: (Choose all the correct choices, marks will be subtracted for incorrect choices.) approximately normal skewed to the left binary discrete binomial skewed to the right symmetric continuous normal c) Give the expected value and standard deviation of p. • Expected value, µp = Round your answer to 2 decimal…
