Answer 1

Since King Queen and Jack are removed, total number of cards left=52-(4*3)=40.

a)No of spades left=13-3=10.
P(spade)=10/40=1/4.
b)No of aces=4
P(ace)=4/40=1/10.
c)Cards spade not ace=9.
P(spade not ace)=9/40.
d)Red coloured cards=26-6=20.
P(red coloured card)=20/40=1/2.

a) 10/40
b)4/40
c) 9/40
