Answer 1

Answer:

(a){62,63,64,68,69}

(b){66}

Step-by-step explanation:

Given the set: {60,61,62,63,64,65,66,67,68,69}

Event X: {x|x is an even number}={60,62,64,66,68}

Event Y: {y|y is a multiple of 3}={60,63,66,69}

Event Z: {z|z is a multiple of 5}={60,65}

Part A

Outcomes that are in event X or in event Y but not in both events. ​

={62,63,64,68,69}

Part B

Outcomes that are in both events X and Y={60,66}

Therefore, Outcomes that are in both events X and Y but not in Z={66}
