Given : A coin is tossed 1000 times, if the probability of getting a tail is ⅜.
Total number of trials = 1000.
It is given that probability of getting a tail = 3/8
Then,
The probability of getting a head , P(H) = 1 - probability of getting a tail
P(H) = 1 - ⅜
P(H) = (8 - 3)/8
P(H) = ⅝
Number of times a head is obtained = ⅝ × 1000 = 625 times
Hence, 625 times head is obtained.
Option (C) 625 is correct .
