Question

Two heads 35 Two tails 23 One head, One tail 52 What is the theoretical probability that a coin toss results in two heads showing?

Answer 1

`Pr = 0.25`

Explanation:

Given

Two heads ---> 35

Two tails ---> 23

One head, One tail ---> 52

Required

The theoretical probability of 2 heads

When a coin is tossed, the probabilities are:

`P(Head) = 0.5`

`P(Tail) = 0.5`

So, the theoretical probability of 2 heads is:

`Pr = P(Head) * P(Head)`

`Pr = 0.5 *0.5`

`Pr = 0.25`

Notice that the given parameters were not used. Using them will only give us the result of the experimental probabilities, because they are recorded from an experiment
