An IT department of a large company estimates that 0.3% of the cases of their security protocol violations are malicious, while the rest are accidental. Further, it is estimated that they result in sig- nificant damages in 60% and 2% of cases respectively. Find the probability that when investigating a particular case where significant damages have occurred, they are dealing with a malicious activity.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

there is nothing below so i cannot

step-by-step explanation:

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
