ella [17]

The most improbable simulation for this coin is the heading when a coin is tossed 20 times will be 15.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A coin is biased to display heads 75% of the time.

It is tossed 20 times, and the outcomes are recorded.

Then the probability of getting heads when a coin is tossed 20 times. Then we have

$\rm P = 0.75 \times 20 = 15$
