At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.14 and the probability that the flight
morpeh [17]

Answer:

The appropriate answer is "0.437".

Step-by-step explanation:

Given:

P(rain) = 0.14

then,

P(no-rain) = 1-P(rain)

                 = 1-0.14

                 = 0.86

P(delay) = 0.16

P(rain and on time) = 0.79

then,

By using the conditional probability, we get

⇒ P(A|B)=\frac{P(A \cap B)}{P(B)}

or,

⇒ P(no \ rain|delay) = \frac{P(no \ rain \cap delay)}{P(delay)}

By substituting the values, we get

⇒                             =\frac{0.07}{0.16}

⇒                             =0.437
