Question

javier volunteers in community events each month. he does not do more than five events in a month. he attends exactly five events 35% of the time, four events 25% of the time, three events 20% of the time, two events 10% of the time, one event 5% of the time, and no events 5% of the time. find the probability that javier volunteers for less than three events each month. p(x < 3) a. 0.25 + 0.35 = 0.60 b. 0.25 + 0.20 = 0.45 c. 0.05 + 0.05 + 0.10 = 0.20 d. 0.20 + 0.05 + 0.05 = 0.30

Explanation:

Step1: Identify relevant probabilities

The events with less than three events are one - event (probability 5% or 0.05), two - events (probability 10% or 0.10) and no - events (probability 5% or 0.05).

Step2: Calculate the total probability

We sum up the probabilities of these events. So \(P(x < 3)=0.05 + 0.05+0.10\).

Answer:

C. 0.05 + 0.05 + 0.10 = 0.20
