Flip a coin 6 times and find the probability of getting 4 heads

15/64 or approx. 23.4% odds

Steps:

Let us count the number of possibilities of getting 4 heads of 6 flips - we do not care about the order within the group of heads so this count is the number of combinations of 4 out of 6, or

The number of all possible outcomes of 6 coin flips is .

So the probability is the ratio

answer: 40.95

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.
