Answer:a) 1/6

b) 5/6

c) 2/3

d) 1/2

e) 1/3

f) 1/2

Explanation:

Probability = no of desired outcome/ no of possible outcomes, a dice has 6 sides therefore, the no of possible outcomes is 6

@) obtaining 4- there is only one four on the dice- probability of obtaining 4 is therefore 1/6

b) we have five numbers other than 4 on a dice- 1,2,3,5 and 6; answer is 5/6

C) we have 4 number not less than 3 on a dice- 3,4,5 and 6 = 4/6; divide both sides by a common number will give 2/3

D) even numbers are2, 4 and 6 are the even numbers on a dice= 3/6; divide by a common number gives 1/3

E) a no less than 3 on a dice are 1 and 2; 2/6; divide by a common no gives 1/3

F) non even no on a dice are 1, 3 and 5: answer is 3/6 which gives 1/2
