Question

a coin is tossed 1200 times . out of which head turned out 720 times . find the probability of getting a tail​

Answer 1

1-720/1200

=1-0.6

=0.4

Answer 2

Here,

Total no. of trials=1200

Getting heads=720

Now, getting tails= total no. of trial - getting head》1200-720=480

Now,

P (getting tail)=480/1200》2/5》0.4
