Theoretical probability is the same thing as experimental probability.

True
False

False

Step-by-step explanation:

Theoretical probability is what is theoretically going to happen, such as the probability of flipping heads is theoretically .5. Experimental probability is based on what has already happened, not what is theoretically going to happen, such as if you flipped heads 10 out of 10 times you flipped the coin, the probability is going to be 1. Since they are different, they are not the same thing, and therefore the statement is false.

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.
