Answer:
The likelihood that a failure will not take place within the next 30 months is 0.0454.
Step-by-step explanation:
We employ a Poisson distribution where:
t = time units
x = occurrences during t units
λ = average occurrences per unit of time
P(x;λt) = e raised to the power of (-λt) multiplied by λtˣ divided by x!
Here, λt equals 25.
x equals 30.
P(x= 30) = 25³⁰e⁻²⁵/ 30!
P (x= 30) = 8.67 E41 * 1.3887 E-11/30! (where E signifies exponent)
P (x=30) = 1.204 E31/30!
Utilizing a statistical calculator will yield:
P (x=30) = 0.0454
The probability that the next failure will not occur prior to 30 months is 0.0454.
¡Hola! Bienvenido a!
Vamos a sumar cuántas canicas tenemos en total.
12+11+17+5=45
Queremos hallar la probabilidad de elegir una canica que no sea azul. Observemos cuántas canicas no son azules.
12+11+5=28
Tendremos esta probabilidad sobre 48.
28/48
Al simplificar, obtenemos 7/12 o alrededor de 58.33%.
¡Espero que esto ayude!
