A number of (= several) attempts have been made.

[heather s]

Hey,

Thanks for your quick reply.

But I have one confusion. Should we need to use,

A number of attempts have been made.

or we can use,

Number of attempts have been made.

Regards,
Heather

Should we need to use,

A number of attempts have been made. Yes - that's why I wrote it, and emphasised the indefinite article.

or we can use,

Number of attempts have been made. No

[heather s]

Thank you...
