20 and 40.
20 + 40 + 40 = 100
Answer:
331
Step-by-step explanation:
You just divide 3,972 by 12.
Answer: The P(e or f) is the P(e) + P(f) when they are disjoint events.
Disjoint events are events that are independent of each other.
Imagine rolling a die. The probability of rolling a 1 is independent of rolling a 2. Both of these probabilities are 1/6.
To find the probability of rolling either a 1 or 2, P(1 or 2) we simply add the 2 probabilities together.
The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
