During a clearance sale, a men’s formalwear store is selling its remaining suits at a discount. Ten percent of the suits have a flawed jacket, 20% of the suits have flawed trousers, and 5% of the suits have both flawed jacket and trousers.
A man buys a suit at random. In the table, indicate what the probability is that the suit will have no flaw, and what the probability is that the suit will have a flawed jacket only.
| No flaw | Flawed jacket | |

| 0.1 | ||

Quote:
Following is known
1) Flawed trouser = 20%
2) Flawed Jacket = 10%
3) Both Flawed = 5%
Thus, we can say that suits with only flawed trouser = (flawed trouser) - Both = 20-5 = 15%
Also, we can say that suits with only flawed Jacket= (flawed Jacket) - Both = 10-5 = 5%
Total Flawed suits as % of total = Only T + Only F + B = 15+5+5 = 25%
So, non-flawed suit = 100-25 or 75%
Solution:
No flaw = 75% or 0.75
Only J = 5% or 0.05

As far as I'm concern the worthest time saver approach is using overlapping sets
Building this model:
Hence solution are 75/100 and 5/100
