Answer 1

Answer:2/3

Step-by-step explanation:

Total probability will be 1

1 - 1/3 =2/3

Answer 2

Answer:

Step-by-step explanation:

Complementary events are

P(A)+ P ( not A) = 1

Given P(A ) = 1/3

1/3+ P( not A) = 1

P( not A) = 1 - 1/3

= 3-1/3

= 2/ 3

So complementary event of 1/3 is 2/3
