Question

find probability of weather forecast do it fastt........ ​

Answer 1

Probability

• The Probability of an event is calculated with the simple logical formula:

• $\textsf{Probability of an event} = \dfrac{\textsf{Number of favourable occurences of event}}{\textsf{Total number of possible events}}$

• Here, the Bar Graph shows the data in Crayonton. The data in tabular format is this:

• $\begin{tabular}{|c|c|}\cline{1-2}\tt Weather Condition &\tt Number of days \\\cline{1-2}\sf Sunny & \sf 3 \\\sf Cloudy & \sf 5 \\\sf Rainy & \sf 2 \\ \sf Snowy & \sf 2 \\ \cline{1-2}\end{tabular}$

• Suppose Event A is that it is Sunny tomorrow in Crayonton. We make this prediction based on the past data.

First, we need the total number of events.

• Total Number of Events = 3 Sunny + 5 Cloudy + 2 Rainy + 2 Snowy = 12 Events

Thus, Total Number of Events is 12.

• Out of that, the number of favourable events, which is Sunny in our case, are 3.

• So, Number of favourable occurrences of Event A = 3
• This is simply because there have been 3 Sunny Days out of 12.

So, Probability of Event A, denoted as P(A), is:

$\sf P(A) = \dfrac{3}{12} = \dfrac{1}{4} \\\\\\ \implies \sf P(A) = \dfrac{1}{4} \times 100\ \% \\\\\\ \implies \Large\boxed{\sf P(A) = 25\ \%}$

Thus,

The Probability that it will be sunny tomorrow in Crayonton is (d) 25 %
