Answer

Explanation:

Step1: Calculate total morning - observed clouds

The total number of clouds observed in the morning is the sum of stratocumulus and stratus clouds observed in the morning. So, $5 + 4=9$.

Step2: Calculate the probability

The probability of a cloud being stratus given it was observed in the morning is the number of stratus clouds observed in the morning divided by the total number of clouds observed in the morning. The number of stratus clouds observed in the morning is 4. So the probability $P=\frac{4}{9}$.

Answer:

$\frac{4}{9}$
