When a dice is rolled , what is the probability of getting :
a ) an even number
b ) an even prime number
c ) multiple of 5

( With all steps and formulas )

When a dice is rolled, then possible outcomes are :1, 2, 3, 4, 5, 6Total number of possible outcomes = 6a.The even numbers are : 2, 4 and 6Number of favourable outcomes = 3So, Pgetting an even number = Number of favourable outcomesTotal number of possible outcomes = 36 = 12b.Th even prime number is 2.Number of favourable outcomes = 1So, Pgetting an even prime number = Number of favourable outcomesTotal number of possible outcomes = 16c.The multiples of 5 are  :5Number of favourable outcomes = 1So, Pgetting multiples of 5 = Number of favourable outcomesTotal number of possible outcomes = 16

a)3/6
b)1/6
c)1/6
there are no steps or formulas for probability....

it is  just a matter of chance..

a) Outcomes =  1,2,3,4,5,6
     Total no. of outcomes = 6
     Favourable outcomes = 3
     P(of getting an even number) = No.of favourable outcomes
                                                             Total no. of outcomes
                                                                 = 3 = 1
                                                                    6    2
Probability of getting an even no.= 1
                                                         2

b)Outcomes= 1,2,3,4,5,6
   Total no of outcomes= 6
  Favourable outcomes= 1
  P(of getting an even prime no.)= No.of favourable outcomes
                                                          Total no. of outcomes
                                      = 1
                                         6
Probability of getting an even prime no.= 1
                                                                   6
c) Outcomes = 1,2,3,4,5,6
   Total no. of outcomes = 6
   Favourable outcomes = 1
   P(of getting a multiple of 5) = No.of favourable outcomes
                                                        Total no. of outcomes
                                               = 1
                                                  6
   Probability of getting a multiple of 5 = 1
                                                                  6
