The vehicle preference of police officers and firefighters is given in the table.
Arisa [49]

Based on the information in the table, an example of independent events is  the: P(policer officer and chooses car).

<h3>What is an independent event?</h3>

An independent event can be defined as an event that isn't dependent on other events. Thus, it isn't affected by any previous event.

Based on the information provided, we can infer and logically deduce that an example of independent events is  the probability of being a policer officer and chooses a car because they aren't overlapping probabilities.

If you make a 25% of discount how much money do you subtract?
pantera1 [17]
Lets say u want an item that originally cost $ 50.....and u get a 25% discount....then u are actually subtracting 25% of the original price.

25% of 50 .....turn the percent to a decimal..." of " means multiply
0.25 * 50 = 12.50.....so u would be subtracting 12.50 from $ 50 for the discounted price which is (50 - 12.5) = 37.5

here is another example...
u want an item that costs $ 90....and it is 25% off.....so u would be subtracting (25% of 90).......u would be subtracting (0.25 * 90) = 22.50 from the original price to arrive at the discounted price.
90 - 22.50 = 67.50...the discounted price

But let me show u something....taking 25% off is the same as paying 75%..
so lets say u want an item that costs $ 60....and u get a 25% discount...this means u r actually paying 75%.....ur paying 75% of 60.
0.75 * 60 = $ 45...this is what u r paying....no need for subtracting
