Sagot :

1.
a. 1, 2, 3, 4, 5, 6
only 4 in numbers 1-6 is a multiple of 4
so 1/6 is the probability
b. numbers less than 5 are: 1,2,3,4
in rolling a dice there are 6 outcomes
so probability is: numbers less than 5/total number of outcomes
probability = 4/6 or 2:3
c. probability = 2/6 or 1/3
d. probability = 3/6 or 1/2
