See the attached picture. You'll find a tree with four branches at level 1 (each of the four sectors of the spinner). Each of these branches is divided in four sub-branches: the possible results of tossing two coins (HH, HT, TH, TT).

So, there are 16 possible outcomes (numbered below each leaf).

If you want to roll an odd number, you have to take branch 1 or 3 at first level.

Then, for each of those, you have to toss exactly one head, so you have to take HT or TH.

The good outcomes are thus 2, 3, 10 and 11, leading to a probability of 4/16=1/4=25%.

Sveta_85 [38]

Answer: 12

Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Hope that helped!!
