1/15
Explicación paso a paso:
Dado que :
Número bolas verdes = 3
Número de bolas rojas = 5
Número de bolas azules = 2
Dibujo sin reemplazo; probabilidad de que el primero sea azul, el segundo sea verde
Probabilidad = resultado requerido / Total de resultados posibles
Resultados posibles totales = 3 + 5 + 2 = 10
P (1er azul) = número de azules / 10
P (1er azul) = 2/10 = 1/5
Sin reemplazo :
Total restante = 10 - 1 = 9
P (segundo verde) = número de verdes / 9 = 3/9
Probabilidad del primer azul y del segundo verde:
1/5 * 3/9 = 3/45 = 1/15
The probability that the first is blue and the second is green is 1/15
Probability is the likelihood or chance that an event will occur.
- Probability = Expected outcome/Total outcome
If a box contains 3 green balls, 5 red balls and 2 blue balls, the total number of balls is 10balls
- Total outcome = 10 balls
- If blue is selected at first, the probability of selecting blue is 2/10 = 1/5
- If green is selected without replacement, the probability of selecting green will be 3/9
- Pr(selecting red and then green) = 1/5 * 1/3 = 1/15
