<span>The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.</span>
Plug in x = 5
f(5) = 2(5) - 4
f(5) = 10 - 4
Solution: f(5) = 6
Nvm wait I read the question wrong. The real answer would be 28, 28, 36
Given that the bag contains 5 apples and 3 oranges, if you select 4 pieces of fruit without looking, the number of ways you can get 3 apples is given by:
we can select 3 apples in 5C3 ways but we are selecting 4 pices, this means that one orange can be selected in 3c1 ways. Using product rule, the total ways to select four pices is
5C3*3C1
=5!/[3!*(5-1)!]×3!/[1!(3-1)!]
=120/(6×2!)*6/(2!)
=12×3
=36
