1 It is known that, on average, 1 in 300 flowers of a certain kind are white. A random sample of 200 flowers of this kind is selected.
- Use an appropriate approximating distribution to find the probability that more than 1 flower in the sample is white.
- Justify the approximating distribution used in part (a).
The probability that a randomly chosen flower of another kind is white is 0.02 . A random sample of 150 of these flowers is 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 .
