Answer 1

Answer:

OUESTION 1

EVEN

OUESTION 2

Cos theta = 1/root 2 Cos theta = cos 45 Theta = 45 Now cot 45 = 1 4+cot 45 = 4+1=5

OUESTION 3

Total no. of cards in pack =52

After removing red face cards - king, queen, and jack

No. of cards =52−6=46

Solution(i):

No. of red cards after red face cards drawn=26−6=20

Therefore, 20C1( Selecting 1 out of 20 items) times out of 46C1( Selecting 1 out of 46 items) a red card is picked.

Let E be the event of getting a red card from pack

We know that, Probability P(E) =(Total no.of possible outcomes)(No.of favorable outcomes)= ²⁰C1 / ²⁰C1 = 20/46 =10 /23.
