Yes, they are independent. First of all, we know that P(A) = 1/4, P(B) = 2/5, and P(A and B) = 1/10. To know if two events are independent, the following questions must be true: P(A)*P(B) = P(A and B). So since (1/4)*(2/5) = 2/20 which equals 1/10, these events are independent

7: In the rhombus, m∠1=10x, m∠2=x + y, and m∠3= 5z. Find the values of x, y, and z.
malfutka [58]
Angles 1, 2, and 3 are all 90°.

10x = 90
.. x = 9

x +y = 90
.. y = 81

5z = 90
.. z = 18

The values of (x, y, z) are (9, 81, 18).
