Question

Each seven day week will contain days that are either dry or rainy. Find the probability of a seven day week where it rains on Sunday and Monday. Express your answer as a decimal.

Answer 1

0.285

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
