There are 45C4 = 148,995 ways to choose 4 calculators out of a group of 45.
There are 33C4 = 40,920 ways to choose 4 calculators that are not defective.
The probability that at least one is defective is (148,995 -40,920)/148,995 ≈ 0.725.
We collect like terms
8x - 3x = 3 + 5 + 9
This is bcos if a (-) sign crosses the equals sign it becomes a (+), and if a (+) sign crosses the equals sign it becomes (-)
We the have
5x = 17
Divide both sides by 5
x = 17/5
x = 3.4
