The value of the probability P(3≤x<7) is 1
<h3>How to evaluate the probability expression?</h3>The expression is given as: P(3≤x<7)
This is calculated using:
P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)
Using the figure of the probability density function (see attachment), we have:
P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20
Evaluate
P(3 ≤ x < 7) = 1
Hence, the value of the expression is 1

She's wrong. If you have two squares, with side
and
with side
, it's not true that the sum of their areas is equivalent to the area of a square
with side
.
So, there's no point in summing the two sides. Instead, you have to compute the areas of the two squares and then sum them up.
So, the area of the first square is , and the area of the second square is
.
Add these two numbers and you'll get how many squared meters of carpet she'll need.
