Johnson has a corporate proposal

Johnson has a corporate proposal. The probability that vice-president Adams will approve the proposal is 0.3. If VP Adams approves the proposal, then the probability that vice-president Baker will approve the proposal is 0.4. If VP Adams doesn’t approve the proposal, then the probability that vice-president Baker will approve the proposal is 0.3. What is the probability that at least one of the two VPs, approves Johnson’s proposal?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
