Question

in a certain weather forecast, the chances of a thunderstorm are stated as 17 out of 100. express the indicated degree of likelihood as a probability value between 0 and 1 inclusive

the probability is
(round to two decimal places as needed.)

Explanation:

Step1: Understand probability formula

Probability is the number of favorable outcomes divided by the total number of outcomes. Here, favorable outcomes (thunderstorm) are 17, total outcomes are 100. So the formula is $P = \frac{\text{favorable}}{\text{total}}=\frac{17}{100}$.

Step2: Calculate the value

$\frac{17}{100}= 0.17$ (since dividing 17 by 100 moves the decimal two places left).

Answer:

0.17
