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 1 0.06 2 0.41 3 0.03 4 0.37 5 0.13

Answer 1

A is ,divisor of 4

P(A) = ?

For every number , 1 in 4 are divisors of 4

4 = 4•1 = 2•2

then probability is sum of

P(A) = P(4) = 0.37

P(2) = 0.41

P(1) = 0.06

P(A) = 0.37 + 0.41 + 0.06 = 0.84

Then answer is

P(A) = 0.84
