Four cards are chosen from a pack of cards without replacement. what is the probability that all four cards are hearts? what is the probability that all four cards are from red suits? what is the probability that all four cards are from different suits?

The total cards in a deck = 52, out of which 26 are black and 26 are red.

Among these 52 cards, Heart = 13 , Spade = 13 , Club = 13 and Diamond = 14

We will use the combination formula as:

1. Probability that all four cards are hearts

=

=

=

= 0.0026

2. Probability that all four cards are from red suits

=

=

= 0.055

3. Probability that all four cards are from different suits

=

=

= 0.105

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
