1/2 ( or 2/4) because half of the cards are black

Solution:

As, in a pack of cards, there are 26 black cards and 26 red cards.

Probability of an event =
\frac{\text{total favorable outcome}}{\text{total possible outcome}}

Probability of drawing a black card from a pack of 52 cards =
(26)/(52)=(1)/(2)

As each card drawn is replaced,Each black card draw is an independent with another black card draw.

Probabilities of drawing a black card on each of four trial=


(1)/(2)* (1)/(2)* (1)/(2)* (1)/(2)=[(1)/(2)]^4
