Answer:

The probability that Joe's stock will go up and he will win in the lottery  is 0.00005.

Step-by-step explanation:

Let the events be denoted as:

<em>X</em> = the stock goes up

<em>Y</em> = Joe wins the lottery

Given:

P (X) = 0.50

P (Y) = 0.0001

The events of the stock going up is not dependent on the the event of Joe winning the lottery.

So the events <em>X</em> and <em>Y</em> are independent of each other.

Independent events are those events that can occur together at the same time.

The joint probability of two independent events <em>A</em> and <em>B </em>is,

P(A\cap B)=P(A)\times P(B)

Compute the value of P (<em>X ∩ Y</em>) as follows:

P(X\cap Y)=P(X)\times P(Y)=0.50\times 0.0001=0.00005

Thus, the probability that Joe's stock will go up and he will win in the lottery  is 0.00005.

Add: f(x)+g(x)<br> f(x) = 2x2 – 3x² + 7x+1<br> g(x) = 4x2 + 5x +12<br> Submit
prisoha [69]

Answer:

f(x) + g(x) = 2x^3 + x^2 + 12x + 13

Step-by-step explanation:

We are given these following functions:

f(x) = 2x^3 - 3x^2 + 7x + 1

g(x) = 4x^2 + 5x + 12

Add: f(x)+g(x)

To add them, we combine the like terms. So

f(x) + g(x) = 2x^3 - 3x^2 + 7x + 1 + 4x^2 + 5x + 12 = 2x^3 + (-3+4)x^2 + (7+5)x + 1 + 12 = 2x^3 + x^2 + 12x + 13

The added function is:

f(x) + g(x) = 2x^3 + x^2 + 12x + 13
