2 equations: the first one is the sum of 2 unknown numbers x and y: x + y = 72. Now the difference is 25, so x - y = 25. Solve the first equation for y: y = 72 - x. Sub that into the second equation to solve for x: x - (72 - x) = 25. x - 72 + x = 25 and 2x - 72 = 25. Therefore, 2x = 97 and x = 48.5 That's the larger of the 2 numbers; since we subtracted y from x we defined x as the larger of the 2. Just for fun, plug x in to find that y = 23.5
Total outcomes of two rolled dice = 6 x 6 = 36
Possibilities for sum of 6 are 3 + 3, 4 + 2, 2 + 4, 5
+ 1, 1 + 5. So total possibilities for sum of 6 are five.
<span>Hence the probability for the sum of 6 = 5/36</span>
The value of y is 1.25 the value of x.
e.g. 6.4 * 1.25 = 8.
Hope this helps! Have a great day :)
Answer:
All events are independent
Step-by-step explanation:
You are given the table

Two events A and B are independent when

a) A="Chocolate"
B="Adults"
A and B="Chocolate and Adults"

Since
events are independent
b) A="Children"
B="Chocolate"
A and B="Children and Chocolate"

Since
events are independent
c) A="Vanilla"
B="Children"
A and B="Vanilla and Children"

Since
events are independent
