Distribution table for the question is attached below :
Answer:
0.533
Step-by-step explanation:
Let :
M = math
D = Drama
Probability that a randomly chosen student takes math or drama ; P(M u D)
Recall:
P(A u B) = p(A) + p(B) - p(A n B)
P(M u D) = p(M) + p(D) - p(M n D)
Probability = required outcome / Total possible outcomes
From the table :
P(M) = 119 / 302
P(D) = 67 / 302
P(M n D) = 25 / 302
Therefore,
P(M u D) = 119/302 + 67/302 - 25/302
P(M u D) = (119 + 67 - 25) / 302
P(M u D) = 161 / 302
P(M u D) = 0.5331125
P(M u D) = 0.533 ( 3 decimal places)
80 * 250 =20,000

7(3) is equivalent to 7 + 7 + 7
7 + 7 + 7 = 21
7 x 3 = 21
hope this helps
<span>Simplifying
3(n + 11) + -5n = -2(n + -12) + 9
Reorder the terms:
3(11 + n) + -5n = -2(n + -12) + 9
(11 * 3 + n * 3) + -5n = -2(n + -12) + 9
(33 + 3n) + -5n = -2(n + -12) + 9
Combine like terms: 3n + -5n = -2n
33 + -2n = -2(n + -12) + 9
Reorder the terms:
33 + -2n = -2(-12 + n) + 9
33 + -2n = (-12 * -2 + n * -2) + 9
33 + -2n = (24 + -2n) + 9
Reorder the terms:
33 + -2n = 24 + 9 + -2n
Combine like terms: 24 + 9 = 33
33 + -2n = 33 + -2n
Add '-33' to each side of the equation.
33 + -33 + -2n = 33 + -33 + -2nCombine like terms: 33 + -33 = 0
0 + -2n = 33 + -33 + -2n
-2n = 33 + -33 + -2n
Combine like terms: 33 + -33 = 0
-2n = 0 + -2n
-2n = -2n
Add '2n' to each side of the equation.
-2n + 2n = -2n + 2n
Combine like terms: -2n + 2n = 0
0 = -2n + 2n
Combine like terms: -2n + 2n = 0
0 = 0
Solving
0 = 0
