Answer 2

A card is drawn from two-pack of cards each, Find the probability that they are black.

Explanation:

• An ideal pack of cards has $52$ cards.
• These each pack of cards there are cards of two colors black and red of equal numbers of $26$ each.
• Now since here, there are two decks of cards the total number of cards is $104$.
• Hence, the number of favorable cards is the total number of black cards available which is $52$.
• Now the probability of drawing two black cards is given by the ratio of the number of ways of selecting two black cards and the total number of ways to select two cards out of all.
• $P(E)=\frac{^{52}C_2}{^{104}C_2} \\->P(E)=\frac{52(51)}{104(103)}\\\\ ->P(E)=0.247 (approx.)$   ------ANSWER
