Question

A bag contains 12 counters numbered from 1 to 12. If a counter is picked at random, find
the probability that is: even, a cube number, prime or odd?

Answer 1

Answer:

Step-by-step explanation:

even (2, 4, 6, 8, 10, 12) = 6/12 = 1/2

cube (1, 8) = 2/12 = 1/6     (although all numbers are a cube of something, just not a whole, or even rational, number)

prime (1, 2, 3, 5, 7, 11) = 6/12 = 1/2

odd (1, 3, 5, 7, 9, 11) = 6/12 = 1/2
