[@poojaola5300]

Thank you so much sir !❤

[@divyayadav5208]

Firstly thank you sir for your support 🙏💯💫 Here in this question given Probability of boy winning Is if red ball numbered 3 and black ball numbered 2 or 1 And given 40% of total red ball is numbered 3 and given reduction total ball is 15 ....then 40% of 15 is =40×15/100 =6 and 45%of black is numbered 2 then 45%of total black ball is 45×20/100=9 Now black ball numbered 1 we have to find given 45% of black numbered 2 and 30% are numbered 3 then 100-45-30=25% is black ball numbered 1...... Now 25%of total ball 25×20/100 =5 Now 6c1+9c1+5c1/35c1 .....( 20+15=35) Now after solving we get 6+9+5/35 =20/35 =4/7 is the required answer

Question solved

[@PrabhatShukla-n5m]

answer 4/7

[@mdmussarafparwez1277]

I have solved q.10

[@vaishalisingh3128]

Q6 shouldnt we add the probability of both of them lying?

[@ArvindKumar-we6ie]

Then they won't be contradicting each other

[@vaishalisingh3128]

Why not? Two truths are same, two lies can be different. If there are 10 balls in a box- A and B look inside, A says there are 11 balls, B says there are 12 balls- both are lies and contradictory.

[@anilaloria4846]

Sir I have solved question no. 10. ans is 4/7

[@varshinip1692]

Can you explain

[@anilaloria4846]

Percentage of red ball numbered 1= 20% or 1/5 2=40%or 2/5 3=40% or 2/5 Similarly for black 1=25% or 1/4 2=45% or 9/20 3=30% or 3/10 Chances of winning is equal to 5c1/35c1 ×2/5 +20c1/35c1 ×1/4 +20c1/35c1 × 9/20 = 4/7 ans.
