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

Select the correct answer. If the number of equally likely sample outcomes of a single stage of an experiment is 4, what is the

mash [69]

Answer:

The total number of elements in the sample space of the experiment for 3 stages = 64 (C)

Step-by-step explanation:

The number of equally likely sample outcomes of the single stage experiment = 4

For n number of stages, the total number of elements in the sample space = (outcome of a single stage)^n

This is = 4^n

To determine the total number of elements in the sample space if the experiment has 3 stages, we would multiply the outcome of one experiment three times.

Where n = 3

The total number of elements in the sample space of the experiment for 3 stages = 4³

= 4×4×4 = 64

The total number of elements in the sample space of the experiment for 3 stages = 64 (C)

A dump truck with 1500 gallons of soil arrives on campus to fill in the new planters on the quad. Each planter needs 2 cubic yar

Tcecarenko [31]

Answer:

3 planters can be filled, with 288,156 gallons left over.

Step-by-step explanation:

Given that a dump truck with 1500 gallons of soil arrives on campus to fill in the new planters on the quad, and each planter needs 2 cubic yards of soil, to determine how many planters can be filled the following calculation must be performed:

1 cubic yard = 201.974 gallons

2 cubic yards = 403.948 gallons

1500 / 403.948 = X

3.71 = X

1500 - (403.948 x 3) = 288.156

Therefore, 3 planters can be filled, with 288,156 gallons left over.
