Conditional probability — practice question

The diagram displays two fair dice. Dice A is labelled 1, 2, 2, 2, 3, 6. Dice B is labelled 2, 3, 3, 4, 4, 4.
(a(i))[1]

Dice A is rolled once. Write down the probability that it shows the number 6.

(a(ii))[1]

Dice A is rolled 150 times. Find how many times it is expected to show the number 6.

(b(i))[3]
