Question

if one coin is toss then find the prolobitity if getting tail ​

Answer 1

✪ᴀɴsᴡᴇʀ✪

• Probability of getting tail is $\frac{1}{2}$

★EXPLAINATION★

• If a coin is tossed once, then the possible outcomes are { H, T}.

• If the given coin is a fair/ unbiased coin, then both outcomes are equally probable.

So,

$\:\:\:\:\: P(H) = P(T).... (1)$

Also,

$\:\:\:\:\: P(H) + P(T) = 1$

$\to P(T) + P(T) = 1$[Using (1)]

$\to 2P(T) = 1$

$\to P(T) = \frac{1} {2}$

• If the coin is biased, P(T) can be any number between 0 and 1.

Answer 2

Step-by-step explanation:

1/2

is the probablity of coming tail.

1/2 is the answer because, the coin has 2 sides :- heads and tails. and there os only 1 tail side that is why 1/2....
