0.285

Step-by-step explanation

The probability formula provides the ratio of the number of favorable outcomes to the total number of possible outcomes. The probability of an Event = (Number of favorable outcomes) / (Total number of possible outcomes)


P(A)=\frac{favorable\text{ outcomes}}{\text{total outcomes}}

then

Step 1

Let

total number of possible ourcomes= 7 ( a seven days week)

Number of favorable outcomes=2 ( Sunday and Morning)

Now, replace


\begin{gathered} P(A)=\frac{favorable\text{ outcomes}}{\text{total outcomes}} \\ P(A)=\frac{2}{\text{7}}=0.285 \\ \text{hence the probability is 0.285 in decimal } \\ or\text{ 28.5 \% } \end{gathered}

so , the answer is 0.285

I hope this helps you
