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:
y = 50
Step-by-step explanation:
y = 2x^2
Let x= -5
y = 2(-5)^2
Power first
y = 2(25)
Then multiply
= 50
Answer:
C : 4√2
Step-by-step explanation:
An triangle has two sides of equal right angles
We call the perpendicular side a, the isosceles triangle FGD at G
According to the Pythagorean Theorem
FH = √FG² + GH² = √a²+ a² => a√2 = 8
⇒a = 4√2
