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

78 must be divided into two even numbers.

The two even numbers should add up to 78: 38 + 40 = 78.

Therefore, the smallest possible even number is 38.

Explanation

Look at how much it increases each time:

Term 1: x  

Term 2: x + 6 → increased by 6  

Term 3: x + 18 → increased by 12  

Pattern of increases: 6, 12, ...  

It goes up by 6 each time. So next increase = 18

Term 4 = Term 3 + 18 = (x + 18) + 18 = x + 36

If we take x = 18, then the terms are 18, 24, 36, 54

Explanation

Put x = -2 and y = 3 in x³y² + x²y  

x³ = (-2)³ = -8  

x² = (-2)² = 4  

y² = 3² = 9  

So x³y² = -8 x 9 = -72  

And x²y = 4 x 3 = 12  

Now add both: -72 + 12 = -60

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}.
