Coin is tossed 1000 times, which means, number of trials are 1000.
Let us consider, event of getting head and event of getting tail be E and F respectively.
Number of favorable outcome = Number of trials in which the E happens = 455
So, Probability of E = (Number of favorable outcome) / (Total number of trials)
P(E) = \(\frac{455}{1000}\) = 0.455
Similarly,
Number of favorable outcome = Number of trials in which the F happens = 545
Probability of the event getting a tail, P(F) = \(\frac{545}{1000}\) = 0.545
