Question

A coin is tossed $100$ times and the following outcomes are recorded
Head : $45$ times Tails : $55$ times from the experiment
a) Compute the probability of each outcomes.
b) Find the sum of probabilities of all outcomes.

Answer 1

Given a coin tossed $100$ times the head is outcomes $45$ times and tails $55$ times.

(a) Then probability of head out comes $=$ $\frac{45}{100}=0.45$

And probability of tails out comes $=$ $\frac{55}{100}=0.55$.

(b) The total outcomes $=45+55=100$

Then probability of all out comes $=$ $\frac{100}{100}=1.00$.
