Part: 0 / 4 Part 1 of 4 Find P(A) - 1 CO X 5

Answer 1

@ P(A)= رد Given A lot contains 10 Componente has u defective items P(A) = first component drawn is defective PCB) = Second Component drawn is defective No q defectives where No = Number Total No of dectives P(A) = 4 P/B/A After drawing there are 3 defective itemy out of a components & Als drawn already P(BLA) : We of defectives » P (B/A) = 99 total he a defective LO P(AMB) = P(A) P(B/A) = x 3 6 45 PANB ال) There are choosix B not independent because Ass drawn it is defective, But will happen only if previously drawn is defective. Since These are not dependent B depends on
