Answer:
0.4231 or 42.31%
Step-by-step explanation:
In a standard 52 card deck there are 13 spade cards (52/4) and there are 12 face cards (4 suits x 3 face cards). Moreover, 3 cards are both face and spade cards.
Therefore, the probability that the card Bashir chooses is either a face card or a spade is given by:
[tex]P(F\ or\ S)=P(F)+P(S)-P(F\ and\ S)\\P(F\ or\ S)=\frac{13}{52} +\frac{12}{52} -\frac{3}{52}\\P(F\ or\ S)=0.4231[/tex]
The probability is 0.4231 or 42.31%
