What is the probability of flipping a coin two times and getting no heads?
If I flip a coin twice and get no heads wouldn't it be 2/2 or 1?
Pr(tt)= 1/2 *1/2
To calculate the probability of getting no heads when flipping a coin two times, we can break it down into individual coin flips.
When flipping a fair coin, we have two possible outcomes: heads (H) or tails (T). Since we want to get no heads, we only want to have tails for both flips.
The probability of getting tails on a single coin flip is 1/2 (or 0.5), since there are two equally likely outcomes (H or T) and only one of them is tails.
To find the probability of a sequence of independent events occurring together, we multiply their individual probabilities. Therefore, for two coin flips, the probability of getting no heads is:
(1/2) * (1/2) = 1/4 or 0.25
So, the probability of flipping a coin two times and getting no heads is 1/4 or 0.25.
