You roll two number cubes let event a = the bumber rolled on the first cube js 6 let event b = the sum of the mubers rolled is 11

D

Step-by-step explanation:

Let A and B be two events as shown in the picture.

We have to say which one we want, and use the symbol "|" to mean "given":

Notion B|A means "Event B given Event A"

In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B?"

P(B|A) is also called the "Conditional Probability" of B given A.

In your case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
