this is a probability question from a Master's course. The scenario is:
Two companies 𝑀 and 𝐻 are in danger of failing, analysts reckon that in the next year: 𝑃(𝑀 fails)=0.7, 𝑃(𝐻 fails)=0.6 and 𝑃(𝑀 and 𝐻 both fail)=0.5 .
- What is the probability that 𝑀 fails and 𝐻 survives?
- What is the probability that both will survive?
My thoughts so far are:
1-0.5 = 0.5, but that is unlikely to be correct.
Probability that at least one will fail is 0.7+0.6−(0.5)(0.7), but I still do not seem to get the correct answer.
Any help is appreciated.
