Combine 2x and positive 8.
2x + 8
Answer:
The probability that at least 1 defective card is in the sample is 
Step-by-step explanation:
Here
N = 140
and n = 20
We will use the below given formula
P(at least 1 defective) = 1 - P( 0 defectives)
P( 0 defectives) =

You answer would be Oy= 7x-1. I hope this helps!
