Two cards are selected from a standard deck of 52 playing cards. The first card is not replaced before the second card is selected. Find the probability of selecting a four and then selecting a king.

0.006%.

Step-by-step explanation:

In a standard deck of cards, there should be four 4 cards and four king cards. We first want the probability of selecting a 4 card, which is just

Then we want it for the king card, but since we didn't replace the first card, we only have 51 cards left. This implies our probability is

Now, all we have left is to multiply the two fractions and divide by the denominator:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
