​

Answer 1

Answer :

(a) 1/6

(b) no chances

(c) 3/6 = 1/2

(d) 3/6 = 1/2

Step-by-step explanation:

(a)3

  1/6 ( a die has six sides each containing no. from 1-6 , so either there got to                                be 1 or 2 or 3 or 4 or 5 or 6 )

(b)7

   no chances (as there aren't any 7 in the die )

(c)an even number

   3/6 = 1/2 (there are three even numbers in an die i.e.- 2,4,6)

(d)a prime number

   3/6 = 1/2 (there are three prime numbers in an die i.e.- 1,3,5)
