Question

One card is drawn from a well shuffled deck of 52 cards. What is the probability of drawing
 (a) a queen (b) a spade (c) a black card​

Answer 1

Answer:

Total cards are 52.

a) out of 52 cards, there are 4 queens

So probability is

$\frac{ { \cancel4} \: ^{1} }{ { \cancel{52}} \: \: ^{13} } \\ \\ = \frac{1}{13}$

b) There are total 13 spades

so probability is

$\frac{ { \cancel{13}} \: \: ^{1} }{ { \cancel{52}} \: \: ^{4} } \\ \\ = \frac{1}{4}$

c)Total black cards are 26

So probability is

$\frac{ { \cancel{26}} \: \: ^{ \cancel2} }{ { \cancel{52}} \: \: ^{ { \cancel4} \: ^{2} } } \\ \\ = \frac{1}{2}$
