Answer:
121 – 1 = 120. 120 – 3 = 117.
Step-by-step explanation:
Answer:
[ry, yr, gy, yg, rg, gr]-Any three picks from this sample space.
Step-by-step explanation:
-The bag contains exactly
marbles.
-He picks one ball without looking, and chooses a second ball without replacing the first:
- If the first is red, the the second is either yellow or green,
- If the first is a yellow, then the second can be red or green,
- If the first is green, then the second can be a red or yellow.
The sample space of the second pick is therefore:
[ry, yr, gy, yg, rg, gr]
Hence, any three picks from the sample space are correct possible outcomes.
Answer:
3 and 63
Step-by-step explanation:
Area = L x W
Area = (y+5) (y-5)
Use Foil to multipy (First, Outer, Inner, Last)
Area = y² -5y + 5y -25
Area = y² -25
