Step-by-step explanation:
2^4/3
2^4 = 16
Then 16^1/3
∛16
Answer:
0.36427
Step-by-step explanation:
Mean = λ = 18 messages per hour
P(X = x) = (e^-λ)(λ⁻ˣ)/x!
P(X ≤ x) = Σ (e^-λ)(λ⁻ˣ)/x! (Summation From 0 to x)
But the probability required is that the messages thay come in an hour is between 15 and 20, that is, P(15 < X < 20)
P(15 < X < 20) = P(X < 20) - P(X ≤ 15)
These probabilities will be evaluated using a cumulative frequency calculator.
P(X < 20) = 0.65092
P(X ≤ 15) = poissoncdf(18, 15) = 0.28665
P(15 < X < 20) = P(X < 20) - P(X ≤ 15) = 0.65092 - 0.28665 = 0.36427.

Answer: The Fuschia Bot clicks _6_ times in 0.75 sec,
Step-by-step explanation:
Multiply the unit rate by time:
.75 sec × 8 clicks/sec
Seconds cancel. .75(8) = 6 clicks
