Answer:
Joint probability table :
_____ A _____ A'
_ Y_ 0.45 ___ 0.30
_ Y'_ 0.05___ 0.20
No
No
Step-by-step explanation:
Given :
Sample, size n = 500
A = driver is under the influence of alcohol :
Y = driver is less than 30 years old
P(A) = 275 / 500 = 0.55
P(Y) = 375 / 500 = 0.75
P(AnY) = 225 / 500 = 0.45
P(YnA') = (1 - 225/375)*0.75 = 0.4 * 0.75 = 0.30
Joint probability table :
_____ A _____ A'
_ Y_ 0.45 ___ 0.30
_ Y'_ 0.05___ 0.20
To determine if it is mutually exclusive : P(AnY) = 0
P(AnY) = 0.45 ; hence, it is not mutually exclusive
For A and Y to be independent ; P(A|Y) = P(A) ;
P(A|Y) = P(AnY) / P(Y)
P(A|Y) = 0.45 / 0.75 = 0.6
Hence, A and Y are not independent.

Answer:
200 and 546
Step-by-step explanation:
dejar a = Primer periodo (first term)
dejar d = Diferencia común (common difference)
dejar 100th término = T100
dejar 273 término = T 273
utilizando
Tn = a + (n - 1)d
T100 = 2 + (100 - 1) 2
= 2 + 99 ×2
= 2 + 198
= 200
T273 = 2 + (273 - 1) 2
= 2 + 272 × 2
= 2 + 544
= 546
According to the condition, this equation has <u>two</u> solutions: -14/5 and 14/5.
Short explanation:
5|x|=14; ⇔ |x|=14/5; ⇒
PS. it's correct, if to substitute the values of 'x' into the condition/equation.
