Probability of picking an even and then even number =
Step-by-step explanation:
Probability of picking a card with even number,
P(even 1) = =
=
=
Followed by picking a card which is even without putting the first card back.
So an even card is to be picked out of remaining 3 cards.
P(even 2) =
=
Now probability of both events = P(even 1) × P(even 2)
=
=
Therefore, probability of both the events will be .
