The departmental photocopier has three parts A, Band C which can gowrong. The probability that A will fail during a copying session is 10-$. The probabilitythat B will fail is 10-' if A fails and 10-5 otherwise. The probability that C will fail is10-' if B fails and 10-5 otherwise. The 'Call Engineer' sign lights up if two or three partsfail. If only two parts have failed I can repair the machine myself but if all three partshave failed my attempts will only make matters worse. If the 'Call Engineer' sign lightsup and I am willing to run a risk of no greater than 1 per cent of making matters worse,should I try to repair the machine, and why?

Imagine an animal that shows two variants; one long-legged and one short-legged. Each female produces 2 female offspring per generation and then dies. The offspring of the long-legged ones survive to adulthood (reproductive age) with a probability of 55% and the offspring of the short-legged ones survive to adulthood with a probability of 45%. If you begin with a population of 60 females of each type, what proportion of individuals will have long legs in 5 generations? (Note that you can ignore males and count only females and their offspring.) Show all work.

Suppose that you were challenged by a friend to hit the bull's eye of a circular board with two concentric circles namely the inner and the outer circles. Your probability of hitting a bull's eye from a distance is 0.05, the probability of hitting the outer circle is 0.75, and the probability of hitting the inner circle is 0.15. If you hit the bull's eye, he will give you 500 pesos. Hitting the inner circle will merit you 300 pesos and the outer circle, 100 pesos. How much is your expected winning? Select the correct response: 265 pesos none of these 95 pesos 145 pesos 335 pesos
