Question

number from 1 to 20 are weitten on paper slips and put in a box. one slip is taken from it. what is the probability that it is an even number? ​

Answer 1

Step-by-step explanation:

total no. of outcomes = 20

even numbers between 1 and 20: 2, 4, 6, 8......20

no. of favourable outcomes: 10

P(getting an even no.) = no. of favourable outcomes/ total outcomes

P(getting an even no.) = 10/20 = 1/2 = 0.5
