Question

A card is drawn from a pack of 52 cards.
What is the probability that,
i) card is either red or black?
ii) card is either black or a face card?​

Answer 1

Step-by-step explanation:

The second derivative of \sf{y = \dfrac{1 + x}{log(x)}}y=

log(x)

1+x

is \begin{gathered}\sf{-\dfrac{1}{(x)log(x)^{2}} + \dfrac{log(x) + 2x + 2}{\big\{(x^{2})log^{3}(x)\big\}}} \\ \\ \end{gathered}

−

(x)log(x)

Explanation :

To find :

The derivative of :

\sf{y = \dfrac{1 + x}{log(x)}}y=

log(x)

1+x

Knowledge required :

Quotient rule of differentiation :

\sf{\dfrac{d}{dx}\bigg(\dfrac{u}{v}\bigg) = \dfrac{v\dfrac{d(u)}{dx} - u\dfrac{d(v)}{dx}}{v^{2}}}
