A coin is tossed 1000 times, if the probability of getting a tail is 3/8, how many times head is obtained?
Possible outcomes of a coin = HT
So here,
there is an equal possibilty of coming of Head and Tail in every toss.
Now it is given that probability of getting a tail = 38
The probability of getting a head = 1 - probability of getting a tail =
The coin is tossed 1000 times.
Hence number of times a head obtained = = 625 times
