Answer #1

Note That Final Value is very nearly equal to same as probability of transmission of electron

but we can see by calculation that it will be something less that electron's probability.

but it is difficult to calculate by calculatorsPlease UpVote and let me know if you face any problem, confusion or see any error.
I will get back to you asap.
