Let V be the event that a computer contains a virus, and let W be the event that a computer contains a worm. Suppose P(V) = 0.17

ArbitrLikvidat [17]

Answer: 0.82

Step-by-step explanation:

The probability of the computer not containing neither a virus nor a worm is expressed as P( $V^{C}$ ∩ $W^{C}$ ) , where P( $V^{C}$ ) is the probability that the event V doesn't happen and P( $W^{C}$ ) is the probability that the event W doesn't happen.

P( $V^{C}$ )= 1-P(V) = 1-0.17 = 0.83

P( $W^{C}$ )=1-P(W) = 1-0.05 = 0.95

Since $V^{C}$ and $W^{C}$ aren't mutually exclusive events, then:

P( $V^{C}$ ∪ $W^{C}$ ) = P( $V^{C}$ ) + P( $W^{C}$ ) - P( $V^{C}$ ∩ $W^{C}$ )

Isolating the probability that interests us:

P( $V^{C}$ ∩ $W^{C}$ )= P( $V^{C}$ ) + P( $W^{C}$ ) - P( $V^{C}$ ∪ $W^{C}$ )

Where P( $V^{C}$ ∪ $W^{C}$ ) = 1 - 0.04 = 0.96

Finally:

P( $V^{C}$ ∩ $W^{C}$ ) = 0.83 + 0.95 - 0.96 = 0.82

I need help on number 1Find 3 point in the graph

kvv77 [185]

$y=-3x-3$

To graph a linear equation:

1. Find the x-intercept

The x-intercedpt is the point when the line cross the x-axis (when y=0)

$\begin{gathered} 0=-3x-3 \\ 3=-3x \\ \frac{3}{-3}=x \\ \\ x=-1 \end{gathered}$

First point (-1 ,0)

2. Find the y-intercept

The y-intercept is the point when the line cross the y-axis (when x=0)

$\begin{gathered} y=-3(0)-3 \\ y=-3 \end{gathered}$

Second point (0 , -3)

3. Put in the plane the x and y-intercepts and draw a line that pass through these points:

Besides the x- and y-intercepts you can identify point (-2,3)

Please i need help!!!

Nezavi [6.7K]

So to divide the 8/9 by 2/9, just divide the numerator of the 8/9 by the numerator of 2/9. 8 / 2 = 4, so there are 4 groups of 2/9 in 8/9.
Then, Toby can make 4 bags of trail mix that are 2/9 pounds each.
Hope this helps!

I think the answer is 15 inches, but i am not sure because you wrote your question kind of stangely in the middle. Hope this helps :)
