Answer 1

option d

Explanation:

Given that a coin is tossed 5 times. Assuming it is a fair coin, head and tail are equally likely.

If we toss 5 times, the number of heads can be either 0 or 1 or 2...5.

Number of outcomes that have 2 heads

=out of 5, two heads and three tails

=5C2

=5(4)/2

=10

So answeris 10
