Home work: P(E`)= both red or both green or both blue or 1red&1blue or 1blue&1green or 1red&1green = 1-(6+10+15+20+30+24)/x =17/38 so x= 190 nC2 =190 n=20 4+5+6+yellow balls = 20 yellow balls = 5 thank you sir jee maa sarvati ke kirpa se apna ek ek sabd samj aata hai

[@Prasad_khisti]

Q 9 was easier and u could do in one glance..... Given that probability of red balls is 2/9 and asks u probality of green or yellow....that is probability of not having red balls.....So probability of red ball is unfavorable here that is P(E') So we can subtract red ball probability from unity to get probality of green or yellow 1-2/9=7/9

[@adarshbharti72]

Probability of green ball is given not red okkkkkk

[@Prasad_khisti]

@@adarshbharti72 probability of green or yellow they asked.....if read my comment u wud know what I'm saying ..... They have given red ball probability that is 2 /9 and asked for green or yellow.....so they actually asked for probability of "no red balls" So they have given you favourable probability and asked for unfavourable By rule - unfavourable + favorable= 1

[@adarshbharti72]

Hw problem Let yellow balls be x then (xc1*15c1+xc2)/15+xc2=17/38 x^2+29x-170=0 x=5.

[@aaryanbali4437]

Bro can you please tell me ,why to took total no of balls 15+xC2 instead of 15+x?

[@MAGICAL_Megumi]

Cause we are only having 2 yellow balls for sample space ​@@aaryanbali4437

[@gandikotavijayadurga4140]

total number of balls are 15+x but as we are taking 2 balls out of all these so we should write 15+xC2

[@Upsciasmotivation8747]

Thnks Sir ❤️❤️❤️😀😀😀😀😀😀😀😀😀😀 I will crack inshallah ❤️ Ameen ❤️

[@educationwithdk843]

Hw Total ball =15+x Let E' be event of drawing 2 ball such that none is yellow. Then, n(E') = 15C2 =105 n(s) = (15+x)C2 = (15+x) (14+x) / 2 so, P (E') = 105 * 2 / (15+x) (14+x) given, P(E) =17/38 P (E) + P(E') = 1 17/38 + 210/ (15+x) (14+x) =1 On solving: (15+x) (14+x) = 380 We get if put x=5 then lhs = rhs . So yellow ball is 5
