Solution

(a) Para encontrar la probabilidad experimental de obtener un 1 o un 6 y que salga cara en un solo intento, primero sumamos el número de veces que ocurrió este evento. Según los datos:

  • 1T ocurrió 12 veces.
  • 6T ocurrió 9 veces.

Entonces, el total de veces que ocurrió este evento es 12 + 9 = 21.

La probabilidad experimental se calcula dividiendo el número de veces que ocurrió el evento entre el número total de intentos. En este caso, el número total de intentos es 110.

Probabilidad experimental = 21 / 110 ≈ 0.191 (redondeado a la milésima).

(b) Para encontrar la probabilidad teórica de obtener un 1 o un 6 y que salga cara en un solo intento, primero calculamos la probabilidad de cada evento individualmente.

La probabilidad de obtener un 1 o un 6 en un dado es 2/6 (ya que hay 2 resultados favorables de 6 posibles).

number cube is rolled three times. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll). The 8 outcomes are listed in the table below. Note that each outcome has the same probability.For each of the three events in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event.Outcomes ProbabilityEEE EOO OEE OEO EEO EOE OOO OOEEvent A: No even numbers on the last two rolls 18Event B: Two or more even numbers 12Event C: An even number on the second roll or the third roll (or both) 34
