Explanation

(5, 2), (-4, k), (2, 1)

A straight line has constant gradient.

\(\frac{k - 2}{-4 - 5} = \frac{1 - k}{2 - (-4)}\)

\(\frac{k - 2}{-9} = \frac{1 - k}{6}\)

\(-9(1 - k) = 6(k - 2) \implies -9 + 9k = 6k - 12\)

\(9k - 6k = -12 + 9 \implies 3k = -3\)

\(k = -1\)

Explanation

(a) 1st bag contains 12 white (W) balls and 8 black (B) balls; 2nd bag contains 10 white (W) balls and 15 black (B) balls.

P(two black balls from the 1st bag and two black balls from 2nd bag)

= \((\frac{8}{20} \times \frac{7}{19}) \times (\frac{15}{25} \times \frac{14}{24})\)

= \(\frac{14}{95} \times \frac{7}{20}\)

= \(\frac{49}{950}\)

(b) P(picking exactly one white ball) = P(WB from 1st bag and BB from 2nd bag) + P(BW from 1st bag and BB from 2nd bag) + P(BB from 1st bag and WB from 2nd bag) + P(BB from 1st bag and BW from 2nd bag)

= \(\frac{12}{20} \times \frac{8}{19} \times \frac{15}{25} \times \frac{14}{24} + \frac{8}{20} \times \frac{12}{19} \times \frac{15}{25} \times \frac{14}{24} + \frac{8}{20} \times \frac{7}{19} \times \frac{10}{25} \times \frac{15}{24} + \frac{8}{20} \times \frac{7}{19} \times \frac{15}{25} \times \frac{10}{24}\)

= \(\frac{42}{475} + \frac{42}{475} + \frac{7}{190} + \frac{7}{190}\)

= \(\frac{238}{950}\)
