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
2	0.16
3	0.16
4	0.05
5	0.02
6	0.27
7	0.12
8	0.17
9	0.01

Explanation:

Step1: Identify relevant probabilities

Event \(A\) is outcome \(\geq4\). So we take probabilities for outcomes \(4,5,6,7,8,9\).

Step2: Sum the probabilities

\(P(A)=0.05 + 0.02+0.27 + 0.12+0.17+0.01\)
\(P(A)=0.64\)

Answer:

\(0.64\)
