Question

when a softball player gets a hit, it can be a single, double, triple, or home run. when josephine is at bat, the probability that she hits a single is 15 percent and the probability that she hits a double is 5 percent. what is the probability that josephine hits a single or a double when she is at bat?
3 percent
10 percent
20 percent
75 percent

Explanation:

Step1: Identificar las probabilidades

La probabilidad de un sencillo es 15% y la de un doble es 5%.

Step2: Aplicar la regla de probabilidad

Para eventos mutuamente excluyentes (no pueden ocurrir al mismo tiempo), la probabilidad de A o B es P(A)+P(B). Aquí, P(sencillo o doble)=P(sencillo)+P(doble).

Step3: Calcular la probabilidad

15% + 5% = 20%.

Answer:

C. 20 percent
