Question

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is divisible by 2". Find P(A). Outcome Probability 1 0.2 2 0.1 3 0.3 4 0.03 5 0.03 6 0.04 7 0.06 0.14 8 0.03 9 0.07 10

Answer 1

Solution

From the info given the numbers divisible by 2 are:

2,4,6,8,10

And the respective probabilities are:

P(2)= 0.1

P(4) =0.03

P(6)= 0.04

P(8) = 0,14

P(10)= 0.07

And addinf all the values we got:

P(A)= 0.1+0.03+ 0.04+ 0.14 +0.07= 0.38
