Question

a card is drawn at random from a well shuffled deck of 52 cards.find the probability of getting neither a face card nor a black card

Answer 1

Let S be the sample space
n(S)=52
Let A be the event of getting a spade card
n(A)=13
P(A)=n(A) /n(S)
=13/52
=1/4
Let B be the event of getting a black card
n(B)=26
P(B)=n(B)/n(S)
=26/52
=1/2
