Question

1) six faces of a die are as shown below.
A. B. C. D. E. A.
if the die is rolled once, find the probability of -
1) 'A' appears on upper face
2) 'D' appears on upper face​

Answer 1

Answer:

(1) S= A. B. C. D. E. A

n(S) = 6

Event A = A. A.

n(A) = 2

p(A) = n(A) / n(S)

= 2/6

= 1/3

(2) S = A. B. C. D. E. A.

n(S) = 6

Event B = D

n(B)= 1

p(A) = n(B)/ n(S)

1/6
