The answer is is as follows

A) The probability that both of them will get exactly two head = 7/16

B) The probability that one of them will get no heads and the other will get three head = 7/512

Step-by-step explanation:

Let The number of possible outcomes we get when two people flip a coin three times be n(s).

n(s)=2∧3×2∧3=2∧6.

and let the number of required outcome be n(A).

n(A)=8C2 (because of arrangement of heads or tail is not important.

then the

(a) probability that both parties will get Exactly 2 heads is

8C2÷2∧6

=7/16.

Also (b) The probability that one will get no heads and the other will get three heads is 8C3÷2∧6×8C8÷2∧6=7/8×1/64

=7/512

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
