Answer 1

What is the chance that a wife surveyed on the same day as her husband will give a mid-range score? A low score?

For mid range : The ans is the probability multiplication since both the events are mutually exclusive. Hence the ans is 55%*30%= 0.165 Same For low range : 0%*10% = 0

What is the chance that a husband surveyed on the same day as his wife will give a hight score? Same as above ans now for High ans is 10%*25% = 0.025 What is the chance a wife NOT surveyed on the same day as her husband will give a mid-range score? A low score? Now a not section multiplication 1st for mid range=5%*25% =0.125 Same as for low range=0%*25% =0

What is the chance a husband NOT surveyed on the same day as his wife will give a high score? For this we just need to look at the not section's probability of husband's high score = 10%
