Question

If you are picking a number from 1 to 20, what is the probability that wou will pick an even number or multiple of three

Answer 1

Answer:

1\2 , 0.3

Step-by-step explanation:

• Even numbers: no. of outcomes ÷ total no. of outcomes

Even numbers between 1 & 20 : 2,4,6,8,10,12,14,16,18, 20

                                                    == 10\20

                                                    == 1\2

• Multiples of 3 : 3,6,9,12,15,18

                             == 6\20

                             == 3\10

                             == 0.3
