Experimental Probability- what are the chances?

1.    When rolling a die 8 times, the following numbers come up:

1, 4, 3, 6, 6, 2, 4, 3.

What are the actual chances of rolling a 3?

1.    When rolling a die 8 times, the following numbers come up:

1, 4, 3, 6, 6, 2, 4, 3.

The probability of getting a 3 is 2/8. Or 1/4. Or 0.25

If we repeated this for 80 trials. How many 3s would we get.?

Hint (do the probability X 80)

1.    We spun the spinner with the numbers 1 to 5 on it 12 TIMES and these numbers come up:

2, 5, 5, 3, 4, 4, 1, 2, 3, 5, 3, 3

What is the chances of getting a 5?

The probability of getting an ODD number on the spinner is 8/12 or 2/3 or 0.66

How many times would you expect to get an odd number if you spin 150 times?  ( times the probability by 150)
