The probability for choosing green and red is \frac{1}{12}

<u>Solution:</u>

Given that , A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble.

We have to find what is the probability of choosing a green marble, not replacing it, and then choosing a red marble?

Now, we know that,

\text { probability of an event }=\frac{\text { number of favourable outcomes }}{\text { total number of outcomes }}

So, total possible outcomes = 1 red + 1 yellow + 1 blue + 1 green = 4

\text { Now, probability for green marble }=\frac{1 \text { green marble }}{4 \text { marbles }}=\frac{1}{4}

And now, total outcomes will be only 3 as we are not replacing the picked marble.

\begin{array}{l}{\text { Then, probability for red marble }=\frac{1 \text { red marble }}{3 \text { marbles }}=\frac{1}{3}} \\\\ {\text { Then overall probability }=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12}}\end{array}

Hence, the probability for choosing green and red is \frac{1}{12}

Probability of choosing a green marble, not replacing it, and  then choosing a red marble is \frac{1}{12}

Step-by-step explanation:

We have 1 red, 1 yellow, 1 blue, and 1 green marble in bag

Total Marbles = 4

Probability of choosing green marble= \frac{1}{4}

Since green marble is not replaced i.e it is not put back into the bag, so

Total Marbles = 4-1 = 3

Probability of choosing red marble= \frac{1}{3}

Now, calculating the probability of choosing a green marble, not replacing it, and  then choosing a red marble

= Probability of choosing green marble * Probability of choosing red marble

= \frac{1}{4}*\frac{1}{3}

=\frac{1}{12}

So, probability of choosing a green marble, not replacing it, and  then choosing a red marble is \frac{1}{12}

Write a polynomial function of least degree with integral coefficients that has the
frutty [35]

A polynomial function of least degree with integral coefficients that has the

given zeros  f(x)=x^4+x^3+9x^2+9x

Given

Given zeros are 3i, -1  and 0

complex zeros occurs in pairs. 3i is one of the zero

-3i is the other zero

So zeros are 3i, -3i, 0 and -1

Now we write the zeros in factor form

If 'a' is a zero then (x-a) is a factor

the factor form of given zeros

\:\left(x-3i\right)\left(x-\left(-3i\right)\right)\left(x-0\right)\left(x-\left(-1\right)\right)\\\left(x-3i\right)\left(x+3i\right)\left(x-0\right)\left(x+1\right)

Now we multiply it to get the polynomial

x\left(x-3i\right)\left(x+3i\right)\left(x+1\right)\\x\left(x^2+9\right)\left(x+1\right)\\x\left(x^3+x^2+9x+9\right)\\x^4+x^3+9x^2+9x

polynomial function of least degree with integral coefficients that has the

given zeros  f(x)=x^4+x^3+9x^2+9x

natulia [17]

Answer:

a. Mean = 20

Sd = 4

b. Probability of X = 20 = 0.1960

Step-by-step explanation:

we have

n = 25

p = 80% = 0.8

mean = np

= 0.8 * 25

= 20

standard deviation = √np(1-p)

= √25*0.8(1-0.8)

=√4

= 2

probability that exactly 20 favours ban

it follows a binomial distribution

= 25C20 × 0.8²⁰ × 0.2⁵

= 53130 × 0.01153 × 0.00032

= 0.1960

Probability of X = 20 = 0.1960
