The outcome A="At least one" means {1,2,3,4,5......n} where n is the maximum possible outcome.
The only other outcome (B) left (i.e. the complement of the above event "at least one") is (B)={0}.
Therefore, by Kolmogorov's second axiom, A and B are complements, and
P(A)+P(B)=1
therefore
P(A)=1-P(B), or in words,
Probability of outcomes of "at least one" is the complement of the outcome of "0" item.
Answer:
360/100=3.6
30 x 3.6 = 108
10 x 3.6 = 36
From the 10 you can multiply by 5. 36 x 5 = 180
10 3.6 = 36
36 + 36 = 72. 108 + 72 = 180
180 + 180 = 360.
Angles are Red-108, Blue-36, Green-180, and yellow-36.
Hope this helped

Answer:
140 individuals were surveyed
42 people are planning on going to the mountains
Step-by-step explanation:
The question is missing the information regarding the percentage of people who said that they were going to each of the possible destinations. After a quick google search I've found that, in the original question, 32% of individuals were going to the beach, 15% to the desert, 23% to major cities, and 30% to the mountains.
If 21 people said they were going to the desert, and that corresponds to 15% of the total number of people surveyed, the number of people surveyed is:

140 individuals were surveyed
Since 30% responded "the mountains", the number of people planning on going to the mountains is:

42 people are planning on going to the mountains
