I had a doubt on how to solve this question

PART-A 1. Around 0.8% of men are blue-green colour-blind and roughly 1 in 5 men is left-handed. Assuming these characteristics are inherited independently, calculate the probability that a man chosen at random will: (a) be both colour-blind and left-handed. (b) be colour-blind and not left-handed. (c) be colour-blind or left-handed. (d) be neither colour-blind nor left-handed. [6]
