An urn contains 5 green balls, 8 red balls and 7 blue balls. Event A is defined as drawing a red ball on the first draw, and event B is defined as drawing a red ball on the second draw. If two balls are drawn from the urn, one after the other and not replaced, what is P(B|A) expressed in simplest form?

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
