a. Packets of kale seeds each have 100 seeds, each of which will grow independently with probability of .98. The manufacturer will issue a refund for the packet if there is more than one seed that doesn't grow. Assuming I bought a packet, what is the approximate probability I will have cause to ask for a refund?
b. Assume the probability in part (a) was equal to .15 (even though it's not). If the seed maker sells 600 packets of kale seeds this season. What is the approximate probability it will issue refunds for more than 100 packets?
