Question

If you flip a fair coin 7 times, what is the probability that you will get exactly 2 tails?

Answer 1

Answer:

see in this -

7 total times the coin is flip

2 times tail

that means -

total time flip subtract times of tail

7-2 =5

5 is the total number of times of head

7/2 is probability of tail

7/5 is probability of head

this is all

ok !!!!

Thanks
