m&m’s chocolate candies come in six different colours. Suppose the colour distribution is as follows:
| Colour | Blue | Brown | Green | Orange | Red | Yellow |
| Probability | 0.12 | 0.23 | 0.17 | 0.16 | 0.22 | 0.1 |
(a) If you randomly select nine m&m’s, what is the probability that exactly three of them are brown?
(b) If you randomly select 15 m&m’s, what is the probability that less than three of them are green?
(c) If you randomly select 175 m&m’s, what is the approximate probability that at least 19% of them are orange?
(d) If you randomly select 250 m&m’s, what is the approximate probability that between 21% and 27% of them are red?
