Question

A coin is tossed 1000 times, if the probability of getting a tail is 3/8, how many times head is obtained?

Answer 1

Answer:

Step-by-step explanation:

It is given that the coin is tossed 1000 times.

Therefore, n(S)=1000

Let,Event A=Getting a tail.

Therefore, p(A)=n(A)/n(S)

Therefore,3/8=n(A)/1000

Therefore,n(A)=3×1000/8

Therefore, n(A)=375.

Now,Let,Event B=Getting a head.

Therefore, n(B)=n(S)-n(A)

=1000-375

=625

Therefore, n(B)=625

i.e,head is obtained 625 times out of 1000 times.

(If u are asked to find the Probability of getting head on the coin, the answer goes as follows-)

Therefore, p(B)=n(B)/n(S)

=625/1000

=5/8

Therefore Probability of getting a head is 5/8.
