Answer 2

Answer:

a). 1/2 ; b). 1/3 ; e). 1/6

Total outcome is 30

a). Favorable outcome is 15 ⇒ the probability of the number was taken is even is 15/30 = 1/2

b). {3, 6, 9, 12, 15, 18, 21 ,24, 27, 30} ⇒ Favorable outcome is 10 ⇒ the probability of the number was taken is multiple of to 3 is 10/30 = 1/3

e). {6, 12, 18, 24, 30} ⇒ Favorable outcome is 5 ⇒ the probability of the number was taken is multiple of to 3 and 6 is 5/30 = 1/6
