Question
The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is divisible by 5". Find P(A).Outcome Probability1 0.072 0.143 0.074 0.075 0.086 0.057 0.328 0.2
Solution
The event A is "the outcome is divisible by 5". From the given outcomes, the numbers that are divisible by 5 are 5 and 10.
The probability of an event is the sum of the probabilities of the outcomes that satisfy the event.
So, we need to add the probabilities of 5 and 10.
From the table, the probability of 5 is 0.08 and the probability of 10 is not given.
If the probability of 10 was given, we would add the probability of 5 and 10 to get P(A).
Since it's not given, we can only say that P(A) is at least 0.08.
