What is the probability that a point chosen at random in the triangle is also in the blue square?

matrenka [14]

The probability that a point chosen at random in the triangle is also in the blue square can be calculated using geometrical definition of the probability:

$Pr=\dfrac{\text{desired area}}{\text{total area}}.$

1. Find the total area of the triangle:

$A_{total}=\dfrac{1}{2}\cdot 6\cdot 9=27\ in^2.$

2. Find the desired area of the square:

$A_{desired}=3\cdot 3=9\ in^2.$

Then the probability is

$Pr=\dfrac{9}{27}=\dfrac{1}{3}.$

Answer: correct choice is B

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than

Fofino [41]

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: $x+2x+x-6=458$

$4x-6=458$

$4x=464$

$x=116$

So on the third day, Aiden read $x-6=116-6=110$ pages.
