Question

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is less than or equal to 2". Let B be the event "the outcome is less than or equal to 2". Find P(A or B). Outcome Probability 1 0.01 2 0.06 3 0.17 4 0.06 5 0.17 6 0.38 7 0.15

Answer 1

We have to use the following formula

`P(A\cup B)=P(A)+P(B)-P(A\cap B)`
