Question

what is probability of getting head by tossing a coin is​

Answer 1

Hey, mate here is your answer:

Answer:

0.5

Step-by-step explanation:

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

The wording of this question is interesting because it's open to interpretation as to what the writer actually means.

For example it could mean: “What is the Probability of flipping a coin ONCE and getting ONE (or a) HEAD?”

or it could mean: “What is the Probability of flipping a coin N TIMES and getting N HEADS?”

I'll answer the first interpretation above and comment on the second interpretation.

Assumption.

1 It is a FAIR coin, that is not biased in any way such that the Probability of getting a HEAD is exactly the same as getting a TAIL.

First Interpretation.

On that basis the Probability of HEADS = the Probability of TAILS = 0.5 = (1/2) = 50%

Second Interpretation.

If we flip the coin more than once, the result of ANY flip has NO IMPACT WHATSOEVER on the result of any subsequent (or OTHER) flip.

Each flip is an INDEPENDENT EVENT.

On this basis if we flip the coin TWICE the Probability of achieving TWO HEADS IS

( 1/2 ).( 1/2 ) = ( 1/4 ) = 25%

If we flip the coin THREE times, the Probability of of achieving THREE HEADS is

( 1/2 ).( 1/2 ).( 1/2 ) = ( 1/8 ) = 12.5%

If we flip the coin N TIMES, the Probability of achieving N HEADS is

( 1/2 )^N = ( 1/2 ) multiplied by itself N times.
