Explanation

To find the distance of the ladder from the wall, we can use trigonometry.

Let's denote the distance from the wall as 'x'. Since the ladder forms a 60° angle with the wall, we can use the cosine function:

cos(60°) = x / 20

We know that cos(60°) = 0.5, so:

0.5 = x / 20

x = 20 × 0.5

x = 10 m

To solve this, we need to follow the order of operations (PEMDAS):

Multiply 6 and 20: 6 × 20 = 120

Divide 120 by 4: 120 ÷ 4 = 30

Subtract 40 from 10: 10 - 40 = -30

Add 30 to -30: -30 + 30 = 0

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
