Question

universal set = { whole numbers from 1 to 10}

A = { 1, 3, 6, 7, 9 }
B = {2, 4, 5, 6, 8, 10 }

1) A number is randomly chosen from the universal set, what is the probability it is a union b?

2) what is the number that represents both A and B sets

Answer 1

Step-by-step explanation:

1) P(B) = No. of outcomes in B

Total no. of outcomes

= 6 = 3

10 5

2) No. that represents both A and B sets = 6
