<u>SOLUTION</u><u>:</u>

<u>what should be added to a²-2ab+b² to get a²-ab-2b² </u>

let the added no is P

  • \pmb{P+(a^2-2ab+b^2)=(a^2-ab-2b^2) }

  • \pmb{P=(a^2-ab-2b^2)-(a^2-2ab+b^2) }

  • \pmb{P=a^2-ab-2b^2-a^2+2ab-b^2 }

  • \pmb{P=ab-3b^2 }

\therefore{\pmb{ab-3b^2 }} should be added to a²-2ab+b² to get a²-ab-2b²

Using this distribution, find the probability
kaheart [24]

Answer:

P = 0.3

Step-by-step explanation:

Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet

When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes

In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved

So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes

From the table that would be; 0.1 + 0.2 = 0.3
