Answer:
The answer is is as follows
A) The probability that both of them will get exactly two head = 7/16
B) The probability that one of them will get no heads and the other will get three head = 7/512
Step-by-step explanation:
Let The number of possible outcomes we get when two people flip a coin three times be n(s).
n(s)=2∧3×2∧3=2∧6.
and let the number of required outcome be n(A).
n(A)=8C2 (because of arrangement of heads or tail is not important.
then the
(a) probability that both parties will get Exactly 2 heads is
8C2÷2∧6
=7/16.
Also (b) The probability that one will get no heads and the other will get three heads is 8C3÷2∧6×8C8÷2∧6=7/8×1/64
=7/512
