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.

Step-by-step explanation:
Add the exponents when you multiply numbers with exponents
Answer:
It would be x < 4.
Step-by-step explanation:
Your answer would be x < 4. This is because with this inequality, x would always be less than 4.
Know This:
<em>If it was less than or equal to 4 feet, it would of been x ≤ 4.</em>
Tips:
<em>Less or equal to: x ≤ 4</em>
<em>Less than: x < 4</em>
<em>More or equal to: x ≥ 4</em>
<em>More than: x > 4</em>
Answer:
67.00
Step-by-step explanation:
Add the numbers.
You get 67.08.
You want it rounded.
So now the answer is 67.00.
