Let's solve your inequality step-by-step.
−5(4x+6)<−18x+6+4x
Step 1: Simplify both sides of the inequality.
−20x−30<−14x+6
Step 2: Add 14x to both sides.
−20x−30+14x<−14x+6+14x
−6x−30<6
Step 3: Add 30 to both sides.
−6x−30+30<6+30
−6x<36
Step 4: Divide both sides by -6.
−6x
−6
<
36

Step-by-step explanation:

F(x) is been calculated by considering X (moderate) as one outcome and low and high combined as one outcome now probability function will be same as binomial distribution

F(x) = [(4! /(x!)*(4-x)!]*[(0.3) ^x]*[(0.7) ^ (4-x)]
