The probability rules states that, if A and B are two independent events, such as in this problem, the probabilty that both events ocurr simultaneously is the multiplication between their probabilities. Because of that we have that:
![\begin{gathered} P\text{ \lparen of being offered both jobs\rparen = P1 \lparen of being offered the first one\rparen * P2 \lparen of being offered the second one\rparen} \\ P\text{ = 0.440 * 0.500} \\ P\text{ = 0.22} \end{gathered}]()
So, the probability of Jennifer being offered both jobs is 0.22, or 22%
