In a certain desert region, 15% of the coyotes are super geniuses while 85% are not. Recent records indicate that 70% of the super genius coyotes will never catch a roadrunner while 90% of the coyotes that are not super geniuses will never catch a roadrunner.
b. If a coyote is randomly chosen in this desert region, find the probability that the coyote is not a super genius and will never catch a roadrunner

please answer all 1. (a) A certain species of bird always lays 3 eggs in the spring, but it is not guaranteed that all of the eggs it lays will hatch. Scientists think that a model for the nunber, X, of eggs that hatch has a probability distribution given by 0 where θ is a parameter to be estimated. i) Given that at least one egg hatches, determine the probability that all three eggs in a nest hatch. 2 marks...
