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
Answer:
19.25 inches
Step-by-step explanation:
x^2 + 5^2 = 8^2= 64
25+ x^2 = 64
x^2 = 64-25= 39
x = 6.24
perimeter = 19.24
Answer:
D:86
Step-by-step explanation:
all three triangle sides always equal 180, so first you find the missing side. As you can see the angle you are finding is complementary to the missing side so its just the 180 minus the first answer.
