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.
Answer:
4 cups of milk chocolate
Step-by-step explanation:
if there are 6 cups in total, then you can see that 1:2 is equal to 3 cups in total. If you multiply both sides of the ratio by 2, then you get 2:4, which is 6. You have to add the chocolate together to find how much it equals in total. Because it's white chocolate to milk chocolate, that would be 2:4, so there are 4 cups of milk chocolate.
