Explanation

Given sequence: 4, 11, 7, 14, 10, 17, __, 20

Two alternating series are used:

First series: 4 → 7 → 10 → 13 (+3 each time)

Second series: 11 → 14 → 17 → 20 (+3 each time)

Missing number: 13

Explanation

A coin has 2 possible outcomes each time:

• Head (H)
• Tail (T)

If the coin is flipped 3 times, the total possible outcomes are:

2^3 = 8 

The possible outcomes are:

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

Only one outcome gives 3 heads: HHH.

Therefore:

Formula

P(3 heads)=Favourable outcomes​/Total outcome=1/8

1/8=0.125 or 12.5%

Explanation

Numbers up to 200 divisible by both 2 and 3 are multiples of 6.

6, 12, 18, 24, …, 198

Formula:

200 ÷ 6 = 33 remainder 2

Total numbers = 33

Explanation

Let the number be x.

3% of x = 60

3/100 x X = 60

X= 60 x 1000/3

$$x = frac{60 times 100}{3}$$ x=2000​

Explanation

The equation |-x| = 0 simplifies to x = 0 since the absolute value of any number is zero only when the number itself is zero.

Therefore, the solution set contains only {0}.
