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
