Question

what is the formula for probablity?​

Answer 1

Answer:

Probability ( E )  = $\frac{ Favourable outcomes }{Total number of Outcomes}$

                           = Favourable outcomes / Total number of outcomes

MARK ME AS BRAINLIEST !!

Answer 2

Answer:

$probability = \frac{no. \: of \: favurable \: outcomes}{total \: no. \: of \: outcomes}$

the formula for probability is given above

more things to know:

➡ the probability of a sure event is 1

➡ the probability of an impossible event is 0

➡ The probability of an event E is such that

0<P(E)<1

➡An event having only one outcome is called an elementary event. The sum of the probabilities of all the elementary events of an experiment is 1.

➡For any event E, P(E) + P(not E) = 1
