When resistors $R_{1}$ and $R_{2}$ are connected in series across a battery of potential difference $V,$ the power dissipated by the resistors are $P_{1}$ and $P_{2}$ respectively. When they are connected in parallel across a battery of potential difference $E,$ the power dissipated is $P_{3}$ and $P_{4}$ respectively. Which one of the following is true?

Number of ways in which they can be divided into equal groups if the players P1,P2,P3 and P4 are in different

The correct option is D (11)!108- we divide 12 people into 4 groups=12!(3!)4.4!- But P1,P2,P3,P4 can be arranged units 4 groups above in 4! ways.=12!×4!(3!)4.4!=11!108

Number of ways in which they can be divided into equal groups if the players $P_{1}, P_{2}, P_{3}$ and $P_{4}$ are in different

The correct option is D $\frac{(11)!}{108}$
- we divide 12 people into 4 groups

$= \frac{12!}{(3!) 4. 4!}$

- But $P_{1}, P_{2}, P_{3}, P_{4}$ can be arranged units 4 groups above in $4!$ ways.

$= \frac{12! \times 4!}{(3!)^{4} . 4!} = \frac{11!}{108}$
