I think the answer to your question is 15 hope this helps
35z^4 + 11z^4<span>
= 46z^4 ...combine like terms
hope that helps</span>
Sample space = {p, r, o, b, a, b, i, l, I, t, y} = 11 possible outcomes
1sr event: drawing an I ( there are 2 I); P(1st I) = 2/11
2nd event drawing also an i: This is a conditional probability, since one I has already been selected the remaining number of I is now 1, but also the sample space from previously 11 outcome has now 10 outcomes (one letter selected and not replaced)
2nd event : P(also one I) = 1/10
P(selecting one I AND another I) is 2/11 x 1/10
P(selecting one I AND another I) =2/110 = 0.018
3 terms are in the expression
The answer is 32 because -45 + 3 = -32 and -39 - 3 = -32
