(i) The random variable X has the distribution B(300, 0.01). Use a Poisson approximation to find P(2 < X < 6). [3] (ii) The random variable Y has the distribution Po(λ), and P(Y = 0) = P(Y = 2). Find λ. [2] ) The random variable $ Z $ has the distribution Po(5.2) and it is given…
Small drops of two liquids, A and B, are randomly and independently distributed in the air. The average numbers of drops of A and B per cubic centimetre of air are 0.25 and 0.36 respectively. (i) A sample of $ 10 \, cm^{3} $ of air is taken at random. Find the probability that th…
In the past the number of cars sold per day at a showroom has been modelled by a random variable with distribution $ \mathrm{Po}(0.7) $. Following an advertising campaign, it is hoped that the mean number of sales per day will increase. In order to test at the 10% significance le…
