Answer 1

Step-by-step explanation:

In a 52 playing cards,

Jacks,queens,kings and aces of red colour are removed

:. Total 8 cards are removed.

Let, the sample space (S) for remaining cards.

:. n(S) = 44 [52-8]

Event A : Getting a black queen

:. n(A) = 2

$P(A) = \frac{n(A)}{n(S)} \\ \\ P(A) = \frac{2}{44} \\ \\ P(A) = \frac{1}{22}$

Event B : A red jack

n(B) = 0 ...{red jack are removed}

$P(B) = \frac{n(B)}{n(S)} \\ \\ P(B) = \frac{0}{44} \\ \\ P(B) = 0$
