From a bag containing 12 identical blue balls, y identical yellow balls, and no other balls, one ball will be removed at random.

If the probability is less than 2/5 that the removed ball will be blue, what is the least number of yellow balls that must be in the bag?

There are y + 12 total balls in the bag. The probability of drawing a blue one is is 12/(y + 12), and the probability of drawing a yellow one is y/(y + 12). We're told that the probability of drawing a blue ball is less than 2/5, so

\dfrac{12}{y+12}

which tells us there must be at least 19 yellow balls in the bag.

In triangle ABC, point D is the centroid, and BD = 6. Find BE.
pshichka [43]

Given:

In triangle ABC, point D is the centroid, and BD = 6.

To find:

The measure of side BE.

Solution:

We know that the centroid divides each median in 2:1.

In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.

Let BD and DE are 2x and x respectively.

We have, BD = 6 units.

2x=6

x=\dfrac{6}{2}

x=3

Now,

BE=BD+DE

BE=6+x

BE=6+3

BE=9

Therefore, the measure of side BE is 9 units.
