Find the probability of each event occurring. There are three vowels out of 6 letters and 1 Q, so the chances of spinning a vowel is 3/6 or 1/2 and the chances of spinning a Q is 1/6. Multiply the probabilities of the two events occurring to find the probability of a compound event. 1/2*1/6 = 1/12. Hope this helps!

Answer:

chisquare = 31.667

degree of freedom = 2

Step-by-step explanation:

Formula for chisquare test = (O-E)²/E

total number observations= 60 + 25 + 15 = 100

Estimated E,

80% x 100 = 80

15%x100 = 15

5% x 100 = 5

chisquare =

$\frac{(60-80)^{2} }{80} +\frac{(25-15)^{2} }{15}+\frac{(15-5)^{2} }{5}\\$

= 5 + 6.67 + 20

= 31.667

from the calculation above the value of the chisquare statistic = 31.67

the degree of freedom is the number of samples in the test n - 1

= 3-1

= 2

I have solve this question also in a tabular form to aid understanding in the file i uploaded.

thank you and good luck!

The equation of line is ,

$\begin{gathered} (y-(-11))=\frac{-3}{7}(x-9) \\ y+11=\frac{-3}{7}x+\frac{27}{7} \\ y=\frac{-3}{7}x+\frac{27}{7}-11 \\ y=\frac{-3}{7}x-\frac{50}{7} \end{gathered}$
