Question

the table gives a set of outcomes and their probabilities. let a be the event \the outcome is a divisor of 4\. find p(a).

outcome	probability
2	0.01
3	0.1
4	0.02
5	0.06
6	0.09
7	0.07
8	0.02
9	0.3
10	0.03

Explanation:

Step1: Identify the divisors of 4

The divisors of 4 are 1, 2, 4.

Step2: Sum their probabilities

$$P(A)=0.3 + 0.01+0.02$$
$$P(A)=0.33$$

Answer:

\(0.33\)
