Jambmaths question:
A card is picked at random from a pack of 52 well shuffled playing cards. Find the probability of NOT picking a red cards in the pack. If there are 13 red card in the pack
Option A:
$\tfrac{3}{4}$
Option B:
$\tfrac{2}{3}$
Option C:
$\tfrac{1}{3}$
Option D:
$\tfrac{1}{4}$
Jamb Maths Solution:
There are 52 cards in a pack of cards. The probability of NOT picking red card is the probability of picking other cards. Which is $Prob({{R}^{1}})=1-\frac{13}{52}=1-\frac{1}{4}=\frac{3}{4}$
