You seem rather desperate. However, nobody is going to give you the answers to these problems. It's against the forum's policy to do so (I think). Show us what you've done and maybe someone will lead you to the answer.

I really dont understand what you have meant by a), b), c), d)
And the question is not clear either. Write the question in a more understanding way and I 'm sure I can help you! supundikadl@yahoo.co.uk

The question is quite straightforward, however, the poster needs to show some evidence of an attempt at solving it.

Take the Poisson formula. Using the information given (namely, 5 new cases) find the parameter value (u) of this Poisson distribution. Then use this distribution to find the answers through plug and chug.

When you be stuck, always fall back on the definitions.
