Kirkland Signature Extra Fancy Unsalted Mixed Nuts 2.5 (LB)

I see walnut in the picture, but not in the description. Can you list all the nuts that are included? Thanks.

This product showed up in my search for "raw nuts" but I don't see anywhere that these are in fact raw vs roasted. Can you verify? Thanks

Are these nuts roasted?

How much do you think a jar serves? Trying to calculate how much to get to have for about 90 guests. We will have other snacks to feed on. thanks.
