Question

plz answer this
plz answer fast as I am having maths exam on 7 march​

Answer 1

Total observations- 52

1- King of red of red or black card=2+26=28
Therefore probability= 28/52
= 7/13
2- face cards=12(king Queen and jack)
Probability= 12\52
= 3/13

3- Queen of diamond or an ace- 1+4=5
Probability= 5/52

4- Club or queen = 13+3=16
Probability= 16/52
= 4/13

Answer 2

Total Cards=52

$\boxed{\mathbf{Probability=\frac{Favourable\: Outcomes}{Total\: Outcomes}}}$

(1)Black Cards=Spades,Clubs

Red Cards=Hearts, Diamonds

Each colour Card have=2 kings.

Favourable Outcomes=2

$\boxed{\mathbf{Probability(Red)=\frac{2}{52}}}$

$\boxed{\mathbf{Probability(Red)=\frac{1}{26}}}$

Black card King will also=1/26
_________________
(2) There are Total =12 face Cards

Favourable Outcomes=12

$\boxed{\mathbf{Probability(Face\:Card)=\frac{12}{52}}}$

$\boxed{\mathbf{Probability(Face\:Card)=\frac{3}{13}}}$

(3) Queen of Diamonds=1

$\boxed{\mathbf{Probability(Queen\:D)=\frac{1}{52}}}$

(4)Club Card=13

$\boxed{\mathbf{Probability(Club\:Card)=\frac{13}{52}}}$

$\boxed{\mathbf{Probability(Club\:Card)=\frac{1}{4}}}$
