Answer:
Amount of Discount: 85, Discounted cost of item: 340
Step-by-step explanation:
You Start by dividing the main price of the item by 100
You then multiply your answer from that by however much the discount is.
We divide by 100 because there is 100 percent when you are paying full price, dividing by 100 gives you the amount that is equal to 1 percent of that price
You then multiply the answer from that by 20, this will give you 20% of the full price, this will give you a discount of 85 Dollars.
To find the Discounted price you then subtract 85 from 425 and you will have an answer of 340 dollars. Hope this helps!

Answer:
the probability that at least one envelope is a yellow envelope is 16/21
Step-by-step explanation:
The probability that at least one envelope is a yellow envelope is P(Y);
P(Y) = 1 - P(Y)'
P(Y)' is the probability that no envelope is a yellow envelope.
Given;
red envelope = 1
blue envelopes = 3
green envelopes = 2
yellow envelopes = 3
Total = 9
Number of non-yellow envelope = 9 -3 = 6
(6 envelope are not yellow)
P(Y)' = P1 × P2 × P3
Since there is no replacement;
P(Y)' = 6/9 × 5/8 × 4/7
P(Y)' = 5/21
From equation 1;
P(Y) = 1 - 5/21
P(Y) = 16/21
the probability that at least one envelope is a yellow envelope is 16/21.
