Question

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

Answer 1

answer = 625 times head obtained

$explanation \:$

$probability \\ = favorable \: event \div total \: event$

total events are 1000

so probability = 3/8

means
8 ratio = 1000
so. 1 ratio = 1000/8 = 125

so 3 ratio = 125 × 3
= 375 times tail

so. head = 1000-375
= 625 times
