MAM CAN YOU EXPLAIN THIS QUESTION-> There are 4 cards 1,3,5,7, one number on one card. Two cards are drawn at random without replacement.let X denote the sum of the numbers on the drawn cards. Find mean and varience of X.

[@lapgandhi]

2 cards are drawn at a time so you could write the sample space as 1,3 1,5 1,7 3,5 3,7 5,7

[@lapgandhi]

X=4,6,8,10,12 as these are possible additions of the sample space

[@lapgandhi]

P(X)= 1/6 for X=4,6,10,12

[@lapgandhi]

P(X)=2/6 for X=8 as there are two possible outcomes for sum to be 8 which are 1,7 and 3,5

[@lapgandhi]

That's it! Find P(X).X then P(X).X^2 Rest you know right. Formula for mean and variance?

[@pokefan2.5]

@@jagpreetbajwa4539 yes please I googled it too there no such thing there

[@pokefan2.5]

Heyy buddy here's your answer I got this from AI To derive tan(3x) = -1 from cos(3x) + sin(3x) = 0: 1. Divide both sides by cos(3x): cos(3x)/cos(3x) + sin(3x)/cos(3x) = 0/cos(3x) 1 + tan(3x) = 0 1. Subtract 1 from both sides: tan(3x) = -1 This derivation uses the identity sin(3x)/cos(3x) = tan(3x). Note: This equation holds true when cos(3x) ≠ 0, as dividing by zero is undefined.

Consider f(x)= x^3 in this case at x=0 also f(x) is increasing. So technically correct definition of strictly increasing function is : f'(x)>=0 where equality holds at discrete points
