Answer 1

Answer:

Total=52 cards

Favorable=red face card or an ACE

Now there are three face cards(king queen jack ) in each house, and there are two red and two black houses.

So, red cards have 3×2=6 face cards-----(i)

Each house has an ACE, so we have 4 ace cards ——————————————(ii)

Thus, toatl no. Of favorable cards

=6+4

=10cards.

Hence, required probability,

=10/52 or 5/26 or 0.19
