Q. 14.2( 44 Votes )

A coin is tossed 1000 times with the following frequencies:

Head: 455, Tail: 545

Compute the probability for each event.

Answer :

Given,


The coin tossed = 1000 times


The total number of trial = 1000


Lets assum,


The event of getting head = E


The event of getting tail = F


Then,


Number of trials in which the E happens = 455


So,


Probability of E =


P (E) =


Similarly,


The probability of the event getting a tail =


P (F) =


Note: we note that P(A)+P(B) = 0.48+0.52


Therefore, A and B are the only two opposite outcomes.
