Answer:
complementary angles
Step-by-step explanation:
Complementary angles are (by definition) a pair of angles the have a sum of 90°.
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
Answer:
Step-by-step explanation:
1 21v - 21
2 3n - 12
3 48x + 18
4 -3b + 9
$200 - 20% savings equals $160 total price
Tax is 6.5%
160X.065 = $10.40 for tax
