Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11

Answer:
1400 is the final altitude
Step-by-step explanation:
Since Lucy descended for four minutes at a rate of 200 feet per minute, we can find how much altitude she lost in four minutes by multiplying 200 by 4. So Lucy descended 800 feet.
To find the final altitude, we take how much she descended and take it away from her starting altitude. So 2200-800 = 1400 feet.
