Question

A coin is tossed 50 times and the head appears 22 times. If we toss the coin randomly what is the probability of getting a tail?​

Answer 1

Step-by-step explanation:

A coin is tossed 50 times

total no.of outcomes = 50.

the head appears 22times

then tail appears =50-heads

=50-22=28times

no.of outcomes=28

probability of getting a tail

=no.of outcomes /total no.of outcomes

=28/50

=14/25

Answer 2

Answer:

A coin is tossed 50 times.

∴ n (S) = 50

Let 'A' be the event where the number of times heads appear :

(No. of times head appear is 22) → given

∴ n (A) = 22

Let 'B' be the event where the number of times tails appear :

So, the number of times tail appeared

= n (S) - n(A)

= 50 - 22

∴ n (B) = 28

∴ P (of getting a tail) = P (B)

= 28/50

= 14/25

∴ The probability of getting a tail is 14/25.
