Lupin seeds are sold in packets of 15 . On average, 9 seeds in a packet are green and 6 are red. Find, to 2 decimal places, the probability that in any particular packet there are
less than 2 red seeds,
more red than green seeds.
The seeds from 10 packets are then combined together.
Use a suitable approximation to find the probability that the total number of green seeds is more than 100 .
