Calculating the probability of coin being biased

Hi all

A coin is tossed 150 times

We know that there are only two possible outcomes, heads or tails, however, we don't know what the probability of each result occurring is.

80 times, it lands on heads
70 times, it lands on tails

What is the probability that heads has a greater than 50% chance of occurring on the next toss?

Any help is appreciated

Re: Calculating the probability of coin being biased

It is a classical p-value test
But I would argue that this test cannot judge probability.

I suggest you read Bayesian statistics. I guess this problem is a false one.
