A.
B.
C.
D.

Using Bernoulli’s Trial Success and
As the coin is tossed 5 times the total number of outcomes will be .
And we know that the favourable outcomes of getting the head even number of times ,successes will be, getting a head,
The probability of success is and of failure is also
the probability that head appears an even number of times

Hence, the correct option is d.
