you roll three six sided dice. what is the probability that exactly two of the dice are odd?
Answer:
3C2 * (.5)^2 * (.5)^1
.375
Step-by-step explanation:
...
The probability that exactly two of the dice are odd is 3/8
What is probability?"It is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is Binomial theorem of probability?[tex]P=~ ^nC_r\times p^r \times q^{n-r}[/tex]
where, p is the probability of success and q is the probability of failure
For given example,
We roll three six sided dice.
We need to find the probability that exactly two of the dice are odd
the probability of success i. e. dice is odd would be,
⇒ p = 3/6
⇒ p = 1/2
So, the probability of failure would be,
⇒ q = 1 - p
⇒ q = 1 - 1/2
⇒ q = 1/2
Also, n = 3 and r = 2
Using Binomial distribution the required probability would be,
[tex]\Rightarrow P=~ ^nC_r\times p^r \times q^{n-r}\\\\\Rightarrow P=~ ^3C_2\times (\frac{1}{2} )^2 \times (\frac{1}{2} )^{3-2}\\\\\Rightarrow P =\frac{3!}{3!(3-2)!}\times \frac{1}{4} \times \frac{1}{2}\\\\ \Rightarrow \bold{P=\frac{3}{8}}[/tex]
Therefore, the probability that exactly two of the dice are odd is 3/8

Step-by-step explanation:
The expression ⁵√p¹¹ is equivalent to the given expression. The correct answer would be an option (C).
What are exponential expressions?Exponential expressions, as the name indicates, involve exponents. We already know that the exponent of a number (base) specifies how many times the number (base) has been multiplied.
The exponential expression is given in the question, as follows:
[tex]p^\frac{11}{5}[/tex]
We have to determine the equivalent expression to the given expression.
As per option (C), we have
⇒ ⁵√p¹¹
The above expression also can be written as:
⇒ [tex](p^{11})^\frac{1}{5}[/tex]
⇒ [tex](p^{11})^{\times}{(\frac{1}{5})}[/tex]
⇒ [tex]p^\frac{11}{5}[/tex]
Hence, we can conclude that the expression ⁵√p¹¹ is equivalent to the given expression.

Which trigonometric functions have the same maximum value?
y = arcsinx and y = arccosx
y = arcsinx and y = arctanx
y = arctanx and y = arcsecx
y = arccosx and y = arcsecx
Answer:
D. y = arccosx and y = arcsecx
Step-by-step explanation:
got it right on edge :)
Answer:
The trigonometric function which have the same maximum value is:
y = arcsinx and y = cos x
Concept:
What are Inverse trigonometric functions?
Inverse trigonometric functions are represented as arcsinx, arccosx, arcsecx, and so on.
The trigonometric functions that are used to calculate an angle from any of the angle's trigonometric ratios are called inverse functions.
The formula which is used to in inverse trigonometric equations are:
arcsinx = -arcsinx
arccosx = pi-arccosx
arctanx = -arctanx
arcsecx = pi - arcsecx
Solution:
The maximum values we obtain from the following equations are:
arcsinx = -1 to 1
arccosx = -1 to 1
arctanx = -pi/2 to pi/2
arcsecx = ∞
So the trigonometric functions which have the same maximum value is arcsinx and arccosx.

John has $100 in his bank account, and is spending $3 a day on lunch. How long until he has $55 in his account?
Answer:
15 days
Step-by-step explanation:
We know that John has $100 in his bank account and he is spending $3 a day.
We want to find how many days until he has $55 left.
d=days
55=100-3d
55+3d=100
100-55=3d
3d=45
Solving for d, we divide by 3.
Your answer is 15.

2/3 x - 1 = 9 - 1/6 x Im supposed to solve but i need some help
Answer:
x=12
Step-by-step explanation:
collect the x stuff on one side
2/3 x + 1/6 x = 9 + 1
5/6 x = 10
x = 12
Answer:
x=12
Step-by-step explanation:
first, you need to get the variable to one side
the easiest way to do it and not deal with negatives would be this way:
2/3x - 1 = 9 - 1/6x
+1/6x +1/6x in order to do this you must first convert the 2/3 to 4/6
to then get
5/6x - 1 = 9
then solve it like normal
5/6x - 1 = 9
+1 +1
5/6x = 10
/ 5/6 /5/6
x=12
