1) Black 2) Red
Section-
i) Answer any Four questions.
ii) Each question carries 4 marks.
If x2 + y2 = 14 xy, then prove tha
2 log(x + y) = 4 log2 +log x + lo​

Answer 1

Answer:

p(getting black card)=26/52=1/2

P(getting red card)=26/52=1/2

Answer 2

Answer:

1/2 and 1/2

x²+y²-2xy=12xy

(x+y)²=2²x3xy

apply logarithm both sides

2log(x+y)=2log2+log3+logx+logy
