The probability that all three randomly selected envelopes are yellow without replacement is 1/84.
<h3>What is a combination?</h3>It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.
We have,
2 red envelopes
2 blue envelopes
2 green envelopes
3 yellow envelopes.
Total number of envelopes = 9
The probability that all three randomly selected envelopes are yellow without replacement.
=
= (3/9) x (2/8) x (1/7)
= (3x2x1)/(9x8x7)
= 1/84
Thus,
The probability that all three randomly selected envelopes are yellow without replacement is 1/84.

Answer:
3/3 = 1
Step-by-step explanation:
The slope formula is..
Pick two formulas. Let's do (-5, -2) and (-2, 1)
x1 y1 x2 y2
(-5, -2) (-2, 1)
=
= 1
It'll work the same thing for (-2, 1) and (1,4)...
3/3 or 1 is a pattern between the points.
Answer:
Please check the explanation.
Step-by-step explanation:
Given
ABC ↔ RQP
It means
- ΔABC ≅ ΔABC
Please check the attached diagram.
Here,
- A ↔ R
- B ↔ Q
- C ↔ P
Parts of ΔABC that correspond to
(i) PQ
From the diagram, it is clear that:
PQ corresponds to CB
(ii) ∠Q
∠Q corresponds to ∠B
(iii) RP
RP corresponds to AC
