Question

Weatherman predicts 50% rain on Saturday and 40% on Sunday. What is the probability it DOESNT rain over weekend

Answer 1

SOLUTION:

Case: Probability

Given:

The table above shows:

R: Rain

NR: No rain

Sat: Saturday

Sun: Sunday

Therefore, the probability it DOESNT rain over the weekend is:

$\begin{gathered} Pr(NR)=\frac{110}{200} \\ Pr(NR)=\frac{11}{20} \end{gathered}$

Final answer:

The probability that it does not rain is: 11/20
