Question

If a fair coin is tossed 5 times, what is the probability, to the nearest thousandth, of getting exactly 2 heads?

Answer 1

When a fair coin is tossed five times, there is a 5/16 chance of getting two exact heads.

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the possibility or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Here,

Total outcomes,

= 2*2*2*2*2

=32

Possibility of getting exactly 2 heads,

=5C2

=5!/3!2!

=5*4/2

=10

Probability of getting exactly 2 heads,

=10/32

=5/16

The probability of getting 2 heads exactly will be 5/16 when a fair coin is tossed 5 times.
