Any event where you want the event to occur randomly on one of the the 7 days of the week.
6-52
The probability is 3/7.
The probability is 5/9.

The sample space is H1, H2, H3, H4, H5, T1, T2, T3, T4, T5.
Assuming the red and blue spinner has an equal number of red and blue spots, the odds of spinning blue is 50%. On the other spinner, the odds of an odd number is 67%. Combined, the odds of spinning blue and an odd number is 33%. (50% times 67%)
There are ten possible events: that the spinner shows one of the number from 1 to 10. The probability of each of these events is the same and equals 1/10, 0.1 or 10%
There are 2*4*6 = 48 possible outcomes in total.

Suppose a game uses a spinner with five equal sections numbered 1-5 to determine the value of tokens given to the player spinning it. What is the expected value of the number of tokens?
It depends on how many sides the spinner has, a detail that was not provided in the question. If the spinner has 7 sides, and there is only one 3, then the probability of landing on a 3 is 1 in 7, or about 0.1429.
