Question

I came across a question: rn A coin was tossed 250 times and 175 times it came out 2 be heads.The coin is tossed again. rn What is the probability og getting a head? rn The answer was 7/10. rn But i think this is wrong rn it should be 1/2 as probability of tossing a coin and getting a result is always 1/2 and does not depend on previus results. So please help me out

Answer 1

1) no of favourable outcomes =175
no of total possible outcomes=250

p(getting heads)= 175/250
=7/10
2)when you toss the coin one time
the probability of getting head or tail =1/2
because
no of favourable outcomes =1(head )
no of total possible outcome s =2
p(getting head)= 1/2
