The lifetime of a lightbulb can be modeled with an exponential random variable with an expected lifetime of 1000 days. a. Find the probability that the lightbulb will function for more than 2000 days. b.

Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 55 times. The results are shown below: A strawberry chew was selected 15 times. A cherry chew was selected 20 times. A watermelon chew was selected 20 times. Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a fraction in simplest form.
In a large population, 67 % of the people have been vaccinated. If 4 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?Give your answer as a decimal to at 4 places
A family has two cars that are insured, a sports car and a commuting vehicle. The probability that the sports car is in an accident in the next 4 years is 0.014. The probability that the commuting vehicle is in an accident in the next 4 years is 0.004. Assuming that accidents are independent events, compute the probability that at least one of the two cars is in an accident in the next 4 years. Use three decimal place accuracy.

On average, TV crash after 17,000 hours of continuous use. Although the time for the TV to crash is random, researchers have found that the duration until the computer crashes follows an exponential probability distribution. a. What is the probability that the TV will fail with a usage time of less than 17,000 hours?b. What is the probability that the TV will crash with a usage time of more than 17,000 hours?c. What is the probability that no TV will fail after more than 17,000 hours of use?d. What do you think about the results of points b and c above! What is the difference?
