Correct option C) 0.98%
<u>Step-by-step explanation:</u>
We know that , there are 2 black ace cards out of 52 cards in a deck & 13 hearts out of 52 cards . Here we have to tell What is the probability of drawing a black ace followed by a heart out of a deck when the cards aren't replaced . Let's find out:
Firstly , a black ace is drawn , so probability :
⇒
Now , A heart is drawn out of 51 cards ( as one black ace is already drawn !):
⇒
So , Probability of occurring both events is :
⇒
⇒
⇒
Percentage = %
Therefore , Correct option C) 0.98%
