If you are dealt 5 cards at random from a standard deck of playing cards, what is the probability that at most 4 of them are spa

alexira [117]

Answer:

Step-by-step explanation:

No of ways in which 5 cards are chosen is $N=^{52}C_5$

No of ways in which at most 4 cards are spades $N_0=$ Total ways-5 spades

$=^{52}C_5-^{13}C_5$

Probability that at most 4 cards are spade $P=\frac{N_0}{N}$

$P=\frac{^{52}C_5-^{13}C_5}{^{52}C_5}$

$P=\frac{2598960-1287}{2598960}$

$P=\frac{2597673}{2598960}=0.9995$

If –1 is a root of f(x), which of the following must be true?

zysi [14]

The correct answer is that a factor of f(x) is (x+1)

This is due to the zero product property, which states that if two binomials multiply to 0, then one of its factors must equal 0.

(x+1) must equal 0.
(x+1)=0
x=-1

If (x-1)=0, then x would equal 1 instead of -1 which is what the question is asking for.
