In the Pirates of the Aegean video game, you may have to investigate o, 1, 2, 3. 4, or 5 grottoes without success before you finally locate a treasure chest. You conclude that the probability you will have to investigate at most x grottoes without success is F(x) P(x s x) l ij and F5) 1. (Remember that n'" (n-1)(n-2)...(n-k+ 1) is the number of permutations (ordered lists without replacement) of k items from n possibilities.) a) What is the probability you will have to investigate exactly 3 grottoes without success? b) What is the expected number ECM) of grottoes you will investigate without success?c) What is the variance Var(M) of the number of grottoes you will investigate without success?

my answer is$ 12

step-by-step explanation:

because 15 -2=12

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?

yes, i heard the "tea" with james charles and a few other beauty gurus. i believe charles is in the wrong and i believe tati the most. tati didn't lie about james charles but may have exaggerated because he never sexually assaulted anyone. jeffery star is a really good friend to all and out anyone that needs it, until you mess with one of his "sisters"! james will never rise over jeffery or tati, he's way to sensitive and dramatic to rise about them. i think all three of them will make up and be friends again because they always get over it.

i hope this with your
