That is very good. Team spirit!

Only 11, but it still counts. And I got around 35 posts today - 12 to math, 10 or so to chem.

This should up your math related posts totals!

Great. Thanks both of you very much!

Yes, I see it now, .46935

P(1 ≤ X ≤ 3) = P(X=1) + P(X=2) + P(X=3) = 0.028 + 0.132 + 0.309 = 0.469 Similarly, P(1 ≤ X ≤ 3) = P(X ≤ 3) – P(X ≤ 0) = 0.472 – 0.002 = 0.470

I am not getting that for 6?!

0.4695 as an average of 0.470 and 0.469

The exact answer for 6 is 0.46935 .

Again, what was your answer for 6?

3 is correct.

Thank-you both very much.

12) Looks to be a good rounding.

0.028 + 0.132 + 0.309 = 0.469 and = 0.472 – 0.002 = 0.470

Hm? There is only one onswer for 6.
