REALLY NEED HELP: The Venn Diagram shows a universe with 26 elements and two different outcomes: B and Y

Goshia [24]

Answer:

P(B|Y)=0.4

Step-by-step explanation:

We are given with a Venn diagram of a universe with 26 elements and two different outcomes: B and Y

And we are asked to find P(B|Y)

The formula for P(B|Y)= $\frac{P(B\cap Y)}{P(Y)}$

From Venn diagram, $P(B\cap Y)=\frac{n(B\cap Y)}{26} =\frac{8}{26} =\frac{4}{13}$

And P(Y)= $\frac{n(Y)}{26}=\frac{8+12}{26}= \frac{20}{26}= \frac{10}{13}$

Hence P(B|Y)= $\frac{(\frac{4}{13})}{\frac{10}{13}} =\frac{4}{10}=0.4$

Sam chose one marble from a bag containing 2 red marbles, 3 white marbles, and 10 black marbles. Find the probability that the m

Anvisha [2.4K]

Answer:

P(black) = 2/3

Step-by-step explanation:

We need to find the total number of marbles

2 red marbles+ 3 white marbles+ 10 black marbles = 15 marbles

To find the probability that Sam chose a black marble, we take the number of black marbles and divide by the total number of marbles

P(black) = black marbles/total marbles

= 10/15

Divide the top and bottom by 5

= 2/3

What is the figure formed?What is the area of the figure?

$\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}$

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

<u>Hence! the figure formed is a square.</u>

What is the area?

$\large{\sf{ \longmapsto Area_{(square)} = s \times s}}$

$\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}$

$\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}$
