When dividing by a negative the answer is always gonna be a negative unless both numbers are negative

So first do 9/3

The answer is 3 because 3 goes into 9, 3 times

Since the 3 in the equation is negative

In the answer the 3 will also be negative

-3

To check your answer

If you multiply a negative by a negative the answer is going to be positive

So, -3 * -3 = 9

Your answer is correct

-3 is the answer

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

Your friend decides to flip a coin repeatedly to analyze whether the probability of a head on each flip is 1/2. He flips the coi

Phoenix [80]

Answer:

Step-by-step explanation:

Given that a friend flips a coin 10 times and observes head 7 times. So he concludes Probability of head =0.1

This is wrong because

i) Just making 10 trials and coming to conclusion is wrong. Trials should be large to get accurate estimate

ii) The way he threw the coin may be biased so differrent persons should flip and get results for larger trials

iii) External influences such as air, any other disturbance is not considered here.

To avoid all these sampling fluctuations number of trials should be increased with different situations and times.
