(a)[3]
Apply a suitable approximating distribution to determine the probability that more than 1 flower in the sample is white.
(b)[1]
Give a justification for the approximating distribution used in part (a).
(c)[3]
The probability that a randomly selected flower of another kind is white is $0.02$. A random sample of 150 of these flowers is then selected. Use an appropriate approximating distribution to find the probability that the total number of white flowers in the two samples is less than $4$.
