Answer:

a) 5/8

Explanation:

You spin a 4 segment spinner with Go to bed hours of: 8pm, 9pm, 10pm, and 11pm.

You also pull a card from 4-card deck that has 0 - 3 hours values.

The values of cards will be:

0:00hours, 1:00hours, 2:00hours and 3:00hours.

From the given details, the total number of time to go to bed, n, would be:

4(segment spinner) + 4(card deck)

= 4 + 4

= 8

The time available after 10pm =

11pm, 0:00hours, 1:00hours, 2:00hours, and 3:00hours.

The chance you go to bed after 10pm will be given as:

Time available after 10 / total number of time

= 5/8

Therefore, the chance you go to bed after 10pm is 5/8
