3.P(E)=636=16. Probability of two different even numbers = Probability of both even * Probability of both different given they are both even. Probability of both even is 12×12=14.
4.The probability of choosing a day which starts with S is 2/7 or you can also express this answer as 0.285 or 28.5%.
5.If the sum of the digits of a number is divisible by 3, then the number is divisible by 3. Some examples of numbers divisible by 3 are as follows. The number 85203 is divisible by 3 because the sum of its digits 8+5+2+0+3=18 is divisible by 3.
