1 answer:
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%.

<h3><u>The two inequalities are:</u></h3>
Let "a" be the number of adult sized t shirts
Let "c" be the number of child sized t shirts
Given that,
Each Adult sized t shirts = $ 5
Each child sized t shirts = $ 2.50
<h3><u>Jerome need at least 200 adults t-shirt</u></h3>Therefore,
Here, we used "greater than or equal to" symbol, since he needs atleast 200 adult t-shirts
<h3><u>Jerome will spend no more than $1500 on t-shirt</u></h3>Therefore,
Here we used, "less than or equal to" symbol, since he will not spend more than 1500
Thus the two inequalities are found
