So if 50 tablets are made and 2 are defective then it’s 50:2. That means for every 50 tablets are made 2 are defective. And since 50 goes into 2000 40 times, you would multiply 40 x 2 to get 80, the number defective tablets
Then we will multiply both sides of the equation by 2 π : x + π ( 1 - x ) = 0 x + π - π x = 0 x ( 1 - π ) = - π / · ( - 1 ) x ( π - 1 ) = π x = π / ( π - 1 )
