प्रत्येक घटना की संभावना, जब एक सिक्का 1000 बार आवृत्तियों के साथ उछाला जाता है: शीर्ष: 455 और पूंछ: 545 है: , The probability of each event, when a coin is tossed for 1000 times with frequencies: Head:455 & Tail: 545 is:

A. 0.455 & 0.545

B. 0.5 & 0.5

C. 0.45 & 0.55

D. 455 & 545

Correct Answer :

A. 0.455 & 0.545

Explanation

Let E and F are the event of the occurrence of Head and Tail, respectively.

Probability of Occurrence of Head P(E) = No. of heads/total number of trials

P(E) = 455/1000 = 0.455

Similarly,

P(F) = No. of tails/total number of trials

P(F) = 545/1000 = 0.545
