Answer:
The probability that the card is an ace is
Step-by-step explanation:
Total number of playing cards = 52
Total number of ace cards = 4
She selects one card at random from the deck.
We are supposed to find the probability that the card is an ace
So, Probability of getting card=
Probability of getting card=
Hence the probability that the card is an ace is
Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.
<h3>What are the critical points of a function?</h3>The critical points of a function are the values of x for which:
At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.
If a function has n critical points, the least possible degree is of n + 1.
From the changes in behavior of the graph, the function has critical points at:
The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.
