Question

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is greater than or equal to 4". Find P(A). Outcome Probability 1 0.08 2 0.06 3 0.35 4 0.14 5 0.09 6 0.14 7 0.14

Answer 1

From our table, we can note that the probability of the event A="greater or equal than 4" will be given by

`P(\text{A)=P(4)+P(5)+P(6)+P(7)}`

which gives

`\begin{gathered} P(A\text{)=0.14+}0.09+0.14+0.14 \\ P(A\text{)=}0.51 \end{gathered}`

therefore, the probability of the event A is equal to 0.51.
