Answer:
Kofi spent the most money.
Step-by-step explanation:
We have been given that Kofi and Ella each have the same amount of money to spend on food shopping. Kofi spends 3/4 of his money and Ella spends 63% of her money.
Let us convert 3/4 into percent.
We can see that is equal to 75%.
Since both have the same amount of money, so 75% will be greater than 63% of same amount. Therefore, Kofi spent the most money.
2 number cubes.
<span>Let A = {the sum of the number cubes is even}
Let B ={the sum of the number cubes is divisible by 2}
Let A = {2,4,6,8,10,12}
Let B = {2,4,6,8,10,12}
</span><span>A ∩ B refers to intersection of events where A intersect B. Intersection refers to the sums that are common between that two events. These sums are both even and divisible by 2.
</span>
The outcomes in A ∩ B are <span>{2, 4, 6, 8, 10, 12}.
</span>All even numbers are divisible by 2.
