A card is drawn from a well shuffled deck of card . calculate the propabality that the card will be 1). A number less than 7. 2). black Card and multiple of 3
3) face Card
Answers
Step-by-step explanation:
Total number of cards in a deck=52
cards less than number 7=(2,3,4,5,6)
that is 5 cards
since there are 4 colours of cards
therefore the number of cards less than 7 will be
=5*4
=20
1-> probability of a number less than 7
= (number of cards less than 7/ total number of cards)
=20/52
=5/13
multiples of 3 are =3,6,9
total 3 cards that are multiple of 3
since both spade and club are black in colour
therefore
number of black card being a multiple of 3
will be
=3*2
=6
2->probability of getting a card that is black and a multiple of 3
=( number of black cards being multiple of 3/total number of cards)
=6/52
=3/26
3- Number of face cards in a deck=16
probability of getting a face card=16/52
=4/13
