**Solution:**

We know that,

P(do not have the same birthday) + P(have same birthday) = 1

0.897 + P(have same birthday) = 1

Thus,

P(have same birthday) = 1 – 0.897

P(have same birthday) = 0.103

**Solution:**

We know that,

P(do not have the same birthday) + P(have same birthday) = 1

0.897 + P(have same birthday) = 1

Thus,

P(have same birthday) = 1 – 0.897

P(have same birthday) = 0.103
