Answer:
y = 5
Step-by-step explanation:
<u>Equation:</u>
m<DGF = m<DGE + m<EGF
<u>Given:</u>
m<DGF = 12y - 5
m<DGE = 5y + 6
m<EGF = 24
<u />
<u>Work:</u>
m<DGF = m<DGE + m<EGF
12y - 5 = 5y + 6 + 24
12y - 5 = 5y + 30
12y - 5y = 30 + 5
7y = 35
y = 5

Answer:
=0.5278
Step-by-step explanation:
a) The first die roll is bigger than the second or the first roll is a 3
Cases for 2 rolls are
(1,1)(1,2)(1,3)....(1,6),(2,1)(2,2)..... (total 36)
We will get 6 cases when they are equal and 15 when 1st is bigger and 15 when 1st is smaller
So
Let A is the event when first roll bigger
B is the event when First roll=3
So
P(A)=15/36
P(B) =1/6
P(A and B)=2/36
So
P(A or B)=P(A)+P(B)-P(A and B)
=15/36+1/6-2/36
=19/36
=0.5278
