It is simple 5 + 7 + 3 + 2 + 8 + 20 = 45
You should try it one more time as the formula is correct. At least try your best or google once before posting a blog. Here is help for you :
∣ A ∪ B ∪ C ∣ = ∣ A ∣ + ∣ B ∣ + ∣ C ∣ − ∣ A ∩ B ∣ − ∣ A ∩ C ∣ − ∣ B ∩ C ∣ + ∣ A ∩ B ∩ C ∣
∣ A ∣ = 15
∣ B ∣ = 20
∣ C ∣ = 25
∣ A ∩ B ∣ = 10
∣ A ∩ C ∣ = 3
∣ B ∩ C ∣ = 5
∣ A ∩ B ∩ C ∣ = 3
Calculate and yow will get the your answer as 45.
thank u.
