Maria is to select one number from the set {60,61,62,63,64,65,66,67,68,69} at random. consider the following three events. event x: the selected number is an even number. event y: the selected number is a multiple of 3. event z: the selected number is a multiple of 5. part a: list the outcomes that are in event x or in event y but not in both events. part b: list the outcomes that are in both events x and y but not in z.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

the answer is  

a.
