Step-by-step explanation:
Using the permutation formula, as the order is important, it is found that the officers can be chosen in 6840 ways.
Each "position" is a different role(president, vice president and secretary), hence the order is important.
<h3>What is the permutation formula?</h3>
The number of possible permutations of x elements from a set of n elements is given by:
In this problem, 3 people will be chosen from a set of 20, hence:
The officers can be chosen in 6840 ways.

Answer:
Step-by-step explanation:
Total number of cards in a deck = 52
Number of red cards = 26
Number of cards not red =
Number of ways to draw not red cards =
Total ways to draw 3 cards =
The probability that none of three cards are red =
[∵ ]
Now , the probability that at least one of the cards drawn is a red card = 1- Probability that none cards are red
Hence, the required probability =
With in quadrant 3, we should expect both and to be negative, so that is positive. The corresponding reciprocal expressions will have the same sign.
Recall that , which means
Also recall that , so
Only the first two options are correct.
Set up slope formula and solved for x.
