Explanation

The pattern in the series appears to be alternating between adding and subtracting.

27 + 5 = 32

32 - 2 = 30

30 + 5 = 35

35 - 2 = 33

33 + 5 = 38

Explanation

When a dice is rolled, there are 6 possible outcomes: 1, 2, 3, 4, 5, and 6.

The numbers greater than 4 are 5 and 6, which are 2 outcomes.

So, the probability of getting a number greater than 4 is:

Probability = Number of favorable outcomes / Total number of outcomes

= 2/6

= 1/3
