Answer:
Formula
probability= no. of possible outcomes/no. of total outcomes
Explanation:
(the sign '/' shows the upon mark. for example 1 upon 2 is 1/2
given,
no. of possible outcomes = all even no.'s between 1-20
no. of total outcomes = 20
even no.'s= 2,4,6,8,10,12,14,16,18,20
possible outcomes = 10
total outcomes = 20
probability of getting an even no. card,
probability = 10/20
=1/2
the probability of getting an even no. is 1/2
