(e) a number greater than 6
(a) a number 4
(d) an even number
(c) a number less than 4
(f) a number less than 7​

Answer 1

b) 2/6
e) 0/6
a) 1/6
d) 3/6
c) 3/6
f) 6/6

Answer 2

Step-by-step explanation:

Let S be an event of throwing a dice.

S=[1,2,3,4,5,6]

Total number of outcomes, n(S)=6.

Let E be the number of favorite outcomes.

P(E)=n(E)/n(S).

(b). E=[5,6]

n(E)=2.

p(E)=2/6=1/3.

(e).E=[0]

n(E)=0

P(E)=0/6=0.

(a). E=[4]

n(E)=1

P(E)=1/6.

(d).E=[2,4,6]

n(E)=3

P(E)=3/6=1/2.

(c).E=[1,2,3]

n(E)=3

P(E)=3/6=1/2.

(f). E=[1,2,3,4,5,6]

n(E)=6

P(E)=6/6=1.
